Exhibit Sketch - The Kettle Drum consists of a speaker driven by a square wave signal generator with a thin rubber membrane stretched tightly above it and a sinked strobe light. The sink between the two elements is variable. Thus the wave appears to freeze or produce a slow motion wave propagating from the center outwards.
