James Whitney’s Lapis (1966) is a classic work of abstract cinema, a 10-minute animation that took three years to create using primitive computer equipment. In this piece smaller circles oscillate in and out in an array of colors resembling a kaleidoscope while being accompanied with Indian sitar music. The patterns become hypnotic and trance inducing. This work clearly correlates the auditory and the visual and is a wonderful example of the concept of synaesthesia.
