PSEUDOSYNAESTHESIA IN VISUAL MEDIA
Wassily Kandinsky
Kandinsky seemed to intend for his paintings to invoke sounds during their viewing. He wanted to "provide a pictorial equivalent for music." In order to achieve this, his work became more and more abstract with time. He felt that by blending sound with visual stimuli, he was moving toward "total art work", which could touch the inner spirituality of us all.
Disney's Fantasia
Several sources have cited Fantasia as seeking to meld visual and auditory experiences. Since I couldn't put the whole video on the web, the best thing to do would just be to watch it, apply what you know about synaesthesia to it, and impress your friends with your vast knowledge! After all, it is a classic.
