Lego. My son loves, he builds all sorts of things-- cars, towers, 'mission control center', space ship etc etc. We keep pieces in big bins. But some of his 'works' are like pieces of art, I find myself not wanting to dismantle them and keep them as 'art'..
Look at this log head container, you can stack one on top of the other.I feel bad I passed up on this in a HK toystore... maybe next time...
