Program noteTriangular Vibrations is an abstract animation based on the vibrations of an idealised drum. The vibrations are analysed into modes, and shown on the screen greatly slowed down. The modes are heard (as sine waves) at normal pitches, but each audible mode is modulated (faded in and out) in accordance with its visual counterpart. There are in fact three superimposed drums at different pitches, coloured respectively red, green and blue in the visual representation. Nine hundred modes are used for each drum.
