This is exactly like the toy you remember, only bigger and with more options. Each plate is cut from 3mm clear acrylic, is 7" (18cm) across, and includes a variety of rings and gears in several sizes. The individual plates work as self-contained sets, or they can be combined with each other to make an ever-increasing number of different patterns.

The laser-cut plate will be shipped directly from Ponoko to you, which means that you'll need to provide your own pins, pin-board (I recommend foamcore), and pens. NOTE! This drawing tool uses pins with sharp points. It is not recommended that you give it to a small child (or foolish grown-up person) who might eat the pins. Eating pins is pretty much always a bad idea.

There's a slightly longer discussion of pins and pens on my page of notes, which also addresses the problem of pen-skid: http://polychroma.com/spiro-info.html

Plate 150 contains outer ring 150, inner/outer ring 150-105, inner/outer ring 105-72, and gear 72. All the patterns shown in this group were drawn using parts from this plate only.
