Mysterians

Mysterians is a three-layer disassembly puzzle. The three layers rotate and slide over each other until they can be taken apart. The three plates look like question marks. Nick Baxter named this puzzle Mysterians.

Solving the puzzle is like solving a labyrinth, moving from turn to turn. Surprisingly, this "maze" has no loop or dead ends, it is 100% unicursal. Nevertheless, people get confused at some point and start going in the opposite direction, ending up at the start. This puzzle is proof that people can get lost in a Belgian maze.
