Hypnograph Drawing Machine
Art, math, or just fun? All three in fact, and hypnotic to watch as well! This set is composed of a plastic base, pen holder, thirteen gears in different sizes, a crank piece, circular paper, and detailed instructions. Choose two gears (one as the fulcrum and one as the drive), attach the crank, place a circular piece of paper on the base, and crank the handle to make the gears spin and move the pen over the paper to create complex and varied drawings. The pen holder can adapt to hold a variety of writing instruments (fine tip pens, markers, pencils, or crayons). Changing the position of the pen on the fulcrum combined with the different sizes of gears creates infinite possibilities of creations. The detailed instruction book explains how it works and how the math works, but figuring it out yourself by playing and tinkering is half the fun! ~ Megan
