12 1×27 beams
24 #3 and #4 Lego Technic axles
48 Lego Technic bushings or half-bushings
There were no nuts or bolts involved, and it assembles in a few minutes! It could use a couple of cross braces for stability, and I could upgrade it with 10-32 threaded nuts and bolts, but it’s fine for now just sitting there looking pretty on my desk.
Each joint is a staple of grid beam construction – the “tri-joint”. As they say in How to Build with Grid Beam, “If a stick won’t make tri-joints, it’s not grid beam, no matter how many holes it has.” Bitbeam’s ability to make tri-joints without helper cross blocks is the fundamental technical difference between Bitbeam and Lego Technic.
For a different kind of Bitbeam rapid prototyping, you can play around with Mr. Doob’s online voxel editor:
This feels like Philosophy 101 and Plato’s Theory of Forms. The ideal cube on the left, a material cube on the right. (Does that make the MacBook the Cave? Okay, now I’ve confused myself.)
