Hi Shapeways fans, Zygmunt's Cube is based on an idea by Zygmunt Kurczewski. Zygmunt suggested a 2x2x2 cube with an additional 12 edge pairs, each of which could rotate by 180 degrees. Oskar modified Zygmunt's idea to make it look like a 4x4x4 cube, using the same cutting trick that he used for Oh Cube. Experts may recognize that this puzzle could be considered a bandaged version of Mike Armbrust's Rubik's 4x4x4 with a partial twist, which you can buy at Mike's Shapeways Shop. Watch the YouTube video. Buy the puzzle at my Shapeways Shop. Read more at the Twisty Puzzles Forum. Check out the photos below. Enjoy! Oskar
