This is a vector file for cutting chess pieces on a cnc machine or laser cutter.

I created this design while learning how to use my laser, it's a good simple project that creates 35, 1.2in hex pieces that can be pushed together to make abstract sculptures. They make a great desk toy or gift because you can engrave a custom logo or name on each piece to make them truly unique. I'll be giving several sets out this Christmas.

This pattern creates about 35 pieces, and the only material you'll need is a 8x8in piece of plexiglas, which I've been able to regularly find at my local home improvement store for $1.50.

35 pieces is enough to build a 6 inch sphere, or a large abstract object. When I was giving these out as promotional items, I gave them out 7 at a time which is enough to be interesting, but only costs $0.30 in material.

This toy is not intended for young children, the edges are mildly sharp and could possibly be a choked on.

I've also included the flash file which I drew this design in. I have a lot of experience in flash so I'm sticking to what I know for now.

A calling card with working planetary gears. Astound your friends, frustrate your nemisii.

(Update: I've moved the gears slightly to the right, reducing the number of cut parts to assemble.)

Felt like the Old School Space Rocket needed a stand to show it off to best effect... and I needed something to play around with automatic tab generation in sketchup.

Here's the result, dressed up to look like a cartoon exhaust cloud.

The Polyalphabetic Substitution Cipher Slide Rule. This is a slide rule to assist with the ciphering and deciphering of polyalphabetically enciphered messages. With it, you can learn a bit about how slide rules work and a bit about crypto at the same time! It also has some added features that let you begin exploring strong crypto.
