The motion and colour choices were made hand in hand. The illusion of depth and motion change dramatically if for example, a pink form is replaced by blue or white. The swatch image illustrates how colours were sampled and tweaked in the earlier concept art prior to use in the animation.
I created many versions adding and removing content. The intention was to create something that sustains interest, balancing colour, form and motion. A zoetrope can only display 12 frames, so the content is looped. Initially the animation can be quite overwhelming, but after a few seconds the viewers understanding settles and a better appreciation of individual elements emerges.
I haven't posted the animation as I felt that would deflate the release of the final piece. The two stills show the animation at the loop and mid way point.
