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 plates 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
This listing is for three plates: 150, 144, and 84. However, if you'd like a different set of three (or even three all the same), please send me a message. There are a lot of possible patterns once you combine the parts from all three plates. I've made a printable PDF of inside patterns, which may be found here: http://polychroma.com/spiro/patternguide.pdf

Reviews of Cycloidal Scribbling-Engine Starter Set
This is great, I really would love to buy this. But $99? Is it possible to make it out of a cheaper material or somehow lower the price?








You can really make some very quick and beautiful artwork with these! I think they'd be a perfect gift for just about anybody!
