Protude Flow is one of the most amazing art installations I have ever seen. Another clip from my archive of videos from the Siggraph conference back in 2001. It is impossible to communicate how it was to experience this thing live through a video. The installation was made by Sachiko Kodama and Minako Takeno. It is a pool of magnetic fluid with one very powerful electro magnet above it. The magnet is controlled by the sound in the room through a microphone.

The experience was something like “this has to be trick photography“. But you are there in the room and it is real…
