Vimeo Festival + Awards Shortlist 2010

I have seen something similar to this before, but not with human intervention.

This presentation is completely live. An artist adds various reagents in small portions to a chemical process to the fluid phase floating on the surface of a liquid. Thus, the color, shape, and texture of the fluid components are dynamically changed and create artistic abstraction.

An interactive monome?

An art installation of tape and patience?
