Or Toshio’s Psychedelic Toilet. Toshio Matsumoto is known to cineastes for feature films such as Funeral Parade of Roses (which I’ve still not seen—sorry, Thom!), but he’s also responsible for a number of experimental films like this one. In Metastasis (1971) we watch a toilet bowl for 9 minutes while the colours and contrast shift continually. Matsumoto said (in a scrambled quote):
I used the Erekutoro Karapurosesu (Electro Color Processor), which is mainly used in the field of medicine and engineering, to create moving image textures Metastasis, I was interested in layering images of a simple object and its electronically processed abstraction. The electronic abstract image is manipulated in a certain rhythm, depicting an organic process.
This might be tedious if it didn’t also have a decent electronic score by Toshi Ichiyanagi. Watch it here.
