Taking one of Elliott's noisemaker classes at HacDC is a lot like practicing chaos magick: you're never sure what you're going to have to work with at any given time, you don't know what sort of result you're going to get until you're halfway through the process, a large part of your instructions will consist of "Let's try this and see what happens," and you're guaranteed lots of funny noises (often modulated with different kinds of light).

Scaring the neighbors is completely optional.
