1964 – Painting Machine(s) – “Larry Flint” (American)

In the movie "What A Way To Go!", "Larry Flint" creates painting machines to produce his abstract art.

Plot
This lavishly produced, big-budget comedy (it cost $20 million in 1964 dollars) stars Shirley MacLaine as Louisa, a widow who is worth $200 million dollars. However, she's convinced that her fortune is cursed, and she wants to give all her money to the IRS. As she explains her sad tale to her psychiatrist, Dr. Stephanson (Robert Cummings), it seems that when Louisa was young she had the choice of marrying rich playboy Leonard Crawley (Dean Martin) or poor but decent Edgar Hopper (Dick Van Dyke). She chose Edgar, but soon he became obsessed with providing a fine home and fortune for her; he got rich but worked himself to death in the process. Despondent, Louisa flies to Paris, where she strikes up a romance with expatriate artist Larry Flint (Paul Newman). When Larry invents a machine that creates paintings based on sounds, he becomes wealthy and famous — and dies. Louisa returns to America, where she figures to break her streak by marrying Rod (Robert Mitchum), a business tycoon who already has lots of money. He resolves to take life easier and becomes a farmer, only to die in a strange accident with a bull. Louisa is drowning her sorrows one night at a sleazy night spot when she falls for second rate entertainer Jerry (Gene Kelly). They marry, and a now-wealthy Jerry develops a relaxed, carefree quality to his act that makes him a huge star, which leads to his being crushed by a mob of his biggest fans. What a Way to Go! boasted a screenplay by Betty Comdon and Adolph Green that featured many amusing film parodies  ~ Mark Deming. 

The manual use of a jack hammer to make loud, random noises before "Larry" discovered automation using a record player, thanks to "Louisa's" idea.

The more painting machines there were, the bigger the mural that could be painted, the more money one could make.
 

Sadly, there are no credits in the above film clip to find out who made the painting machines.

Paul Newman as "Larry Flint", an ex-patriot artist living in Paris. Shirley MacLaine as "Louisa", looking for the simple life.

"Larry" develops abstract painting machines consisting of a controllable arm with a paint-brush "hand".

He explains to "Louisa", "The sonic vibrations that go in there. And that gets transmitted to this photoelectric cell which gives those dynamic impulses to the brushes and the arms. And it's a fusion of a mechanised world and a human soul."

"Larry" uses a siren, horn, alarm bell, bongo, sledge hammer and a pneumatic jack hammer amongst other things as random sound sources for his abstract art.  "Louisa" hates the loud noise and suggests playing classical music on a record player instead. The music, in turn, is picked-up by  the "sonic palette" and "Larry" is over the moon in excitement over the wonderful results produced. However, "Louisa" says she prefers the real "Larry" produced art, and not the automated "Mendelssohn" inspired pieces.

As "Larry" gets more successful, you see multiple painting machines, mainly painting a mural together on a single, long canvas. The final scene shows the eight painting machines, now painted a gold colour and having an extended arm, plus two newer painting arms, which now have a longer boom arm, and a spine-like end-effector holding a brush, rather like an elephant's trunk. Ten machines in all.  These wrap around "Larry" during the final crescendo, then all the other painting machines encircle "Larry" holding him down, then simultaneously blow themselves up along with "Larry". So much for auto-destructive art!

In reality, the painting machines are props, manned by a person inside each base. This is evident when the bases move around by themselves, and the shape of them allows the hidden person to see what they are doing. The arm itself is fully articulated, and controlled by the person within the base.  The credits may conform this but I have not seen the credits.

Clearly a parody of the Swiss-French Kinetic Artist Jean Tinguely, who had made a name for himself making "Meta-matic" abstract drawing machines.

There is also a scene whereby we hear gunshots, only to find "Polly" shooting at paint balloons on a canvas creating a type of destructive art piece. Again clearly a parody to the late Niki de Saint Phalle who was an artist friend, later wife to Jean Tinguely who were both living in Paris at the time. Niki's early paintings of this period (1961) included her "Shooting Paintings."


 


Note: 2012. I first saw this movie on TV in black and white. I must have been about 12 years old at the time. The painting machines certainly inspired me.  It's taken me over 40 years, thanks to the internet, to locate this film. Wonderful to see again after all this time.

1950c – NERISSA Artificial Nerve – W. Grey Walter (British)

NERISSA.- A Nerve Excitation, Inhibition and Synaptic Analogue.
This demonstrates particularly the relationship between the various parameters of nervous action such as finite propagation
rate, excitation threshold, all-or-none conduction, strength-duration curves of excitability, refractory periods, Wedensky synaptic facilitation and inhibition, inhibitory escape and rebound, transmission of information by pulse interval modulation, and anomalies of " inhibition of inhibition " and " inhibition of inhibition of inhibition " during rhythmic as opposed to sustained stimulation.

Nov 28 [Vivian Walter to Edmund C. Berkeley]
“…..He [Grey] will be most interested to hear of your recent work on the Tortoises, and he is xxxx? for Mr. Warren (of the BNI) to see the transistorised tortoise which Mr. Ruchlis is working on, & I believe sending over here.
If you are interested in “Cora” [sic] ‘Neurisa’ the nerve which Grey had invented & used for lecturing he can let you have any information you require. …..”
 
RH Notes: 
  1. Interesting cross out of “Cora” and replaced by “Neurisa” the nerve. Holland mentions “an electric model of nerve” quoting Walter – 1953 pp 284-286. See also Hayward p631 regarding the naming of models and gender. Young’s book on Cybernetics also mentions NERISSA (Nerve Excitation, Inhibition, and Synaptic Analogue.)  – note different spelling.

W. Grey Walter’s Tortoises – Self-recognition and Narcissism

Self-recognition and the Mirror Dance

[Image source: An Imitation of Life,  Scientific American, May 1950, p42-45.]

7 . Self-recognition. The machines are fitted with a small flash-lamp bulb in the head which is turned off automatically whenever the photo-cell receives an adequate light signal. When a mirror or white surface is encountered the reflected light from the head-lamp is sufficient to operate the circuit controlling the robot's response to light, so that the machine makes for its own reflection; but as it does so, the light is extinguished, which means that the stimulus is cut off — but removal of the stimulus restores the light, which is again seen as a stimulus, and so on. The creature therefore lingers before a mirror, flickering, twittering, and jigging like a clumsy Narcissus. The behaviour of a creature thus engaged with its own reflection is quite specific, and on a purely empirical basis, if it were observed in an animal, might be accepted as evidence of some degree of self-awareness. In this way the machine is superior to many quite 'high' animals who usually treat their reflection as if it were another animal, if they accept it at all.

What can be seen or determined in the photo of Elsie below?  

1. tracer candle visibility;

2. low batteries (because it enters the hutch which is strategically placed to the right of the mirror).

Figure 7. Elsie performs in front of a mirror, but is probably responding to the candlelight rather than to her pilot light. [RH 2010 -Most earlier comments by others are of this rather un-clear image of the so-called 'mirror dance'.]

Prior to the release of the clearer Life image of Elsie performing the 'mirror dance' (see pic below) Holland in "Legacy of Grey Walter" describes it as follows:

Recognition of self
A pilot light is included in the scanning circuit in such a way that the headlamp is extinguished whenever another source of light is encountered. If, however, this other source happens to be a reflection of the headlamp itself in a mirror, the light is extinguished as soon as it is perceived and being no longer perceived, the light is again illuminated, and so forth. This situation sets up a feedback circuit of which the environment is a part, and in consequence the creature performs a characteristic dance which, since it appears always and only in this situation, may be regarded formally as being diagnostic of self-recognition. This suggests the hypothesis that recognition of self may depend upon perception of one’s effect upon the environment.


The below from Discussions on Child Development,  1971, see Book II 1954-56 p35-6.

p35.

With Fig. 6 we come to some of the refinements which emerged only some time after these creatures had been made. This mode of behaviour and the next one were, quite frankly, surprising to us though, of course, we ought to have been able to predict them. Fig. 6 illustrates the situation when a creature of this type is confronted by its reflection in a mirror. It has on its nose a small pilot light, put in originally to tell us what was happening inside; it is so arranged
p36.
that it is turned off when the creature sees another light; that is, it tells us when the photo-tropistic mechanism is in operation.
In this case, the light which the creature was allowed to see was its own pilot light in the mirror. In this situation, the act of 'seeing' it makes it automatically extinguish the light which it sees. The apparent stimulus light having been extinguished, it turns it on again, then off and so on, so that you get a characteristic oscillation. You can see how peculiar and regular it is by the zigzag going up the side of the mirror. This is an absolutely characteristic mode of behaviour, which is seen always and only when the creature is responding to its own reflection. This is an example of the situation I described in the second proposition, where the reflexive circuit includes an environmental operator; in such a situation you get a characteristic mode of behaviour which occurs always and only when the model is reacting to itself.


Narcissism

“The creature therefore lingers before a mirror, flickering, twittering and jigging like a clumsy Narcissus” (Grey Walter, 1963, p. 115). Grey Walter interpreted this famous mirror dance as evidence of self-recognition.

The drawing of the famous `mirror dance’ in `An imitation of life’ [from Scientific American] is nothing like the regular alternation between the tortoise's approach and avoidance as shown in the photograph, being an altogether more irregular and complex trajectory. There may well have been a mirror dance that could have been argued to be a form of self-recognition, but unfortunately this photograph cannot be said to be a record of it. The brightest light visible to the camera, and presumably to the photocell, is the candle on the tortoise’s back and its reflection in the mirror. The trace is far more likely to reflect the alternation of behaviour pattern P (approach to the reflected candlelight) with behaviour pattern O (obstacle avoidance on contact with the mirror). We can be sure that Walter used this image as an example of the mirror dance because it appears in the form of a diagram in the transcript of a talk he gave in 1954 (Walter 1956b); the text matches closely the account given in `Accomplishments of an artefact’. Interestingly, the description of the mirror dance in de Latil’s book also matches this photograph rather than Grey Walter’s original description and Bernarda Bryson Shahn’s sketch.


For most people, with regards to the image above (see figure 7), one could hardly refer to this behaviour as "flickering, twittering and jigging like a clumsy Narcissus". However, you could do so to the above illustration by Bernarda Bryson (partner and later married to the artist Ben Shahn), as illustrated in Scientific American (Walter, W. Grey, "An Imitation of Life," Scientific American, May 1950, p42-45.). The above illustration is actually of Elmer, and not Elsie as is the below photo. This also gives more credence to Grey's use of the word Narcissus, being the son of a Greek god who became obsessed by his own image. [Elmer scans clockwise, the opposite of Elsie and the bump aviodance traverse therefore is from right to left. see here.]

[Narcissus : In Greek mythology, a beautiful youth who fell in love with his own reflection. He was the son of the river god Cephissus and the nymph Leriope. His mother was told by a seer that he would have a long life, provided he never saw his own reflection. His callous rejection of the nymph Echo or of his lover Ameinias drew upon him the gods' vengeance: he fell in love with his own image in the waters of a spring and wasted away. The narcissus flower sprang up where he died.]

Although Elmer was then long gone, Grey Walter continued to use this more interesting description of self-recognition along with the below image, although it didn't and couldn't match with the sometimes erratic behaviour of the original tortoise, Elmer  and could no longer be reproduced with the newer models.

In my opinion, in the cycloidal trace seen above, the 'bottom' of the cycloid appears flattened and bright spots at the start of the cycloid 'flats' appear. To me, this is indicative of 'bump' avoidance behaviour, not self-recognition.  When I visited the Bristol Robot Labs in 2009 to see the replica tortoises, the comment was passed to me that they were unable to satisfactorily reproduce the self-recognition behaviour as described by Grey Walter.


A relatively recent , clearer image of the so-called 'mirror dance' as released by Life Magazine.

A comment on Time-Lapse Photographs in General:
In interpreting all the time-lapse photographs, there are several aspects to keep in mind.
As already mentioned in pervious posts on the Tortoises, the cycloidal gait makes Elsie traverse to the right as her scanner turns in a counter-clockwise direction. Elmer, on the other hand, scans clockwise and because of the trailing action of the rear-wheels, will veer to the left. I must say, though, that the illustrations suggest that with no light source to track towards, Elmer tends to move in a forward direction and not sideways.
Most of the pictures show Elsie heading towards a light, either a candle or the hutch light, sometime a light out of sight near the camera.
Where you see two identical Elsies, it is actually the photographer’s technique of photographing Elsie at the start of the run, then  Elsie at the end of the run. There are not two separate Tortoises except where they look physically different i.e. Elmer has the ‘scaled’ Bakelite sheeting shell. The single trajectory is also an indicator of only a single Tortoise being traced.

Notice also that the flame of the target candle is placed at the same height as the PEC (the Photo-Electric Cell) in the scanning turret.
