fair amount of the action in invocation is totally symmetrical, in this
instance to illustrate the idea that Time and Necessity were two aspects of
the same entity. this meant that the animation only needed to be drawn and processed
once, then flipped over to create its mirror image. the artwork is made of black
paper with holes drilled in it which is backlit when it's being shot. the image
can be tinted either by a gel on the lighted panel beneath the artwork or through
a coloured filter at the lens. the diffusion was created using a diffusion filter
fixed under the lens.../>

there is no better technique than painting with light to create an impression
of otherwordliness and intangibility. this image was built up from two layers,
the egg [turquoise] and the snake [green] that surrounds it. the path that
the snake was to follow was matted out during the exposure of the egg. the
film is rewound and the second exposure is made. this has to be done carefully
in order not to degrade the black background with overspill of light. this
sequence was originally shot on 16mm film which made it much harder to edit
out any mistakes.../>

turn out.../>
