Kinetic art: autonomous spherical robots exhibiting complex motion

As of Saturday night, the pieces for all 6 orbs have been cut! Rich Humphrey, Jon Foote, Rick Lellinger, Lisa Schile, and myself worked two marathon sessions totalling more than 20 hours to keep the Omax Model 55100 abrasive waterjet machine running. The result is more than 500 cut ribs, giving us a few to spare beyond the 480 necessary to fabricate 6 orbs.
