Wallace & Gromit Flip Magnas

Puzzles with not one but two solutions! Each of the 16 tiles has two pictures and no two pictures are the same... but to solve the puzzle every row, column and diagonal can have only one of each of the famous Wallace & Gromit characters..!  Getting one set correct is a challenge... but both at the same time?  That's something else altogether! The puzzle flips from one view to the other as you rock it.
