Modular Origami Bedlam Cube


Tiffany and I celebrated our 8th anniversary last year. Because we were married May 13th, the Fibonacci sequence popped into my head (particularly the 5,8,13 part). So to commemorate this special day I romantically created a Modular Origami Bedlam Cube. I choose the Bedlam cube, not to represent the state of our household, but because it is a thirteen piece puzzle made predominately of pentacubes, thus achieving the 5 & 13. Additionally, I wanted to embed the Fibonacci sequence, so I created a clear plastic ‘0’ piece using the single tetracube, then created the other pieces in color groups for the next numbers in the sequence. Each piece, besides the ‘0’ piece, was created using a modular origami technique from mini-post-it notes. The number of modules needed matches the number of faces of the pieces. Putting them together is pretty straightforward but takes some practice, especially for the inward corners. I found using a straight pin to push from the inside helped shape the pieces.
The modules are a great thing to do waiting at the bus stop (or proctoring an ACT) because they easily slip into your pocket.
If you’ve mastered the soma cube and snake cube, this 4x4x4 puzzle is a good next step. This great resource can help if you get stuck and just need a solution. It also alerted me to the Big Brother cube, a very similar puzzle which uses a different set of 12 pentacubes from the 29 possible that I have yet to try.

Happy building.
