Oskar's Blocks

A very beauty 3 piece puzzle, existing from 3 incomplete cubes to make an interlocking 3 dimensional symmetric sculpture.

Oskar's Two Piece Packing

Two very irregular shaped polyominopieces must be interlocked and then they will fit into the 4x4x4 box.
A very seldom produced puzzle
