Puzzle Boy

On Friday we had dinner at PoPo and Ojiisan's house. Sven finished his dinner early, so he was playing with one of Ojiisan's puzzles in the living room. It was an Adam's Cube and I thought he was randomly playing with the pieces. I saw him drop and retrieve the pieces on the floor and couch a few times, then after 30-40 minutes he said "hey I made a big square." He had managed to get the pieces back in the correct square pattern. This is a puzzle that several adults can't even manage (including this Mommy).

The picture of the puzzle shows another pattern that can be made with the same pieces.

1/2/08 update: Sven played with this toy again yesterday during New Year's Dinner, and did this Rocket.
