Abacus and Square Root Wall Art

I'm a fan of colorful things in baby and kids rooms.  Last year, I put this abacus in my son's room above his crib. It's a nod to learning while looking good, too.

And then I came across this in the latest CB2 catalog. Different than the abacus, but with a similar color palette and feeling, this square root wall art would be equally great in a kids room, bedroom or living room.

Such a great, playful quality in both.  Aren't they fun?
