Nine pendula, each having a two-line mount, vary from slightly fewer to slightly greater than 20 swings every 20 seconds. With a simultaneous start, the bobs make a very captivating wave-like parade that shows all the possible phase relationships before returning to unison and starting over again. The rigid interlocking frame (21-5/8 in. W x 18-7/8 in. H) provides offset sharp edges to support each pendulum.
