What is this? It's 20lbs of flour over a speaker. What is playing out of that speaker? A really really loud noise. It's static from an amplifier turned to full (these go to eleven). With out the flour snuffing out the sound, it would be ear splitting. It is beautiful and terrifying at the same time. If you look close you can see the grains for flour falling down gently.
I love it, its going in the show.
Now I just need to make it interactive...
