I've been going to these for a few years now and always have a great time. Put on by the good folks at McNeel and Associates, makers of Rhinoceros, and hosted by Bob, Dave and Pete, it's a great experience. I've gotten to play with tools I'd never otherwise have access to, learn from pros and network with other 3d teachers to see what's up. I only wish it were in September to give me a little impetus for the year. This year I designed and cut the Lego Graboid from green neon acrylic. Way too cool.
Laser cutter working on wood prototype
Done - Mmmmm, smoky!
Completed prototype - Lego compatible
Pricy Neon acrylic - $20 /sheet
Love that neon. Note the lego axles
Might as well do a 4 arm version.
