The sound of the sound installation Wave of Matter is created in a way similar to the ocean drum we had at our house when I was young. Only this one is square, and huge. Due to its square form factor it produces short waves of noise, unlike the ongoing whoosh of an ocean drum. This does make it a bit less interesting, sonically.
This good looking installation was created by Tommi Grönlund and Petteri Nisunen, an artist duo based in Helsinki.
