Craft Horizons July/August 1954

A composition of Lissajous figures which are produced by a means of a series of swinging pendulums whose vibrations are registered graphically. The patterns were achieved by Professor Alfred Gysi of Zurich. The figures shown on the cover are similar to but not identical with those in Graphis 16. Blogged at Aqua-Velvet.
