Here are 2 other installations from the From Spark to Pixel exhibition. First: Hemisphere by Ulf Langheinrich. You had to lie on the floor under a gigantic hemisphere on which abstract animations where projected together with sound and stroboscopes. You had to lie there to experience it, but maybe this video gives you an idea.
An other installation was Ondulation by Thomas McIntosh. It's basically a thin layer of water with some speakers beneath it. Due to the position of the speakers and the different frequencies, amazing wave patterns appeared. The water surface mirrored the light onto the wall so you could see the effect better.
There are some more pictures and 2 videos on the website.
