A classic in the art of optical sound, Dresden Dynamo apparently resulted of an accidental discovery. When applying Letratone to a blank 16mm film soundtrack, Rhodes noticed that it produced a C note; she then composed several images with Letraset, of which she developed positive and negative copies, and later applied color filters in order to develop two-color contrasts. By allowing these compositions to encroach into the soundtrack, Rhodes creates relatively stable sound drawings that are an aural translation of the printed screen, thus expanding on earlier experiments by McLaren, among others. The result is a mind-bending experiment in which the interaction between simple geometrical, aural and chromatic patterns generates infinite illusory events and in which colour and shape subtly pervert one another, forcing foreground and background to constantly change positions in order to conjure depth and movement. -- Lux
