I made a video of myself playing with a Binary Burr made Maurice Vigouroux.

The Binary Burr is a puzzle designed by Bill Cutler. The goal of the puzzle is to remove the main piece by moving all the locks according to repetitive pattern. Each extra lock doubles the number of moves necessary to open the puzzle.

This version has 15 locks, and needs 43690 moves to be opened. Surprisingly enough, it is possible to perform all these moves in less than 3 hours.

In the video, I only perform 169 moves. Don't be afraid, it takes only 25 seconds from move 1 to move 169 :)
