Noah Prettyman designed this wonderful new burr puzzle with the intention to recreate the standard six piece burr shape using puzzle cube type pieces. A very unique idea, and a successful one given the unique level 6.3 solution. Knotted burr is a lot of fun to solve and is quite difficult despite its reasonable seeming number of moves. I'm looking forward to whatever he comes up with next!
