Like something out of a 3D Tetris game, Remember Bricks are described as:
A game, an object, a puzzle, a sculptur, an artwork, an architecture, a building set, a creation, a model, an enjoyment, a fun, simply ingenious. For young and old and tall and small.
Whatever the intepretation, these blocks are highly adorable, and I could see myself building all kinds imaginative cities with them.
You can purchase them here.
