The folks over at BustedBricks.com offer hobby supplies and laser cutting services. To this useful list, they will soon be adding the nifty little rolling ball sculpture shown in the video as a kit! The video shows a test version of the kit. The final version will have a an easy-to-assemble laser cut plywood track, which does not require soldering skills or equipment. I adore the laser cut gears!
The kits will be available on Friday of this week at www.bustedbricks.com. I'm thinking these would make great holiday gifts. In the meantime, I recommend you check out the Stirling Engine Kits they currently offer!
