Hi Shapeways fans, Bram's Shuffle is a twisty puzzle invented by Bram Cohen. It has seven pillowed tetrahedrons that slide around inside a pillowed octahedron. The object is to scramble the puzzle and solve it again. All the tetrahedrons have six degrees of freedom, as they can fully change position and orientation. This makes the puzzle hard and confusion to solve. Related puzzles are Bram's Black Hole and Bram's Rocket. Watch the YouTube video. Watch the video of the initial failed prototype as well. Buy the puzzle at my Shapeways Shop. Read more at the Twisty Puzzles Forum. Check out the photos below. Enjoy! Oskar
