I created an edition of about 100 of these lased puzzle kits to give away at FITC Amsterdam. A total of 24 sides and 270 holes makes 4 'unwhole' cubes when fully assembled.
The design is my own creation. The vectors (tooth geometry and circle packing) for the laser cuts were created with code written in ActionScript 3. I hope to release the code open source, but right now it is a mess, like my hair.
