BonBon by Frederic Boucher, made by CubicDissection.
"BonBon is also just a ton of fun. The set of five tetrominoes must be fully inserted in the rectangular box, and there is only one particular way to do it. The solution requires over a dozen correct moves and rotations. It must be found by careful analysis rather than random attempts."
