How much fun can a box be?

(Please ignore the amateurish photoshop eraser job!)

Thanks to my husband, my son has discovered the wonders of a box! I didn't know a box could be so much fun. They have made houses, car ramps, bridges that wobble, and slides, among other things. Not only does he get quality time with his dad (his favorite buddy) doing something that he loves, but he is learning all sorts of things about how cars and other objects roll, how his body feels when he walks, stands, sits, or slides on different objects, he is learning about construction, and we have done puppet shows out of his houses so he is learning stories, language and a little bit about theater. Plus, it's been great bonding time for our whole family. You can't beat that.
