Kids design at its most simple - let the kids create the use of the object. Like the amazing lure of another multi-use fun thing, Silly Putty, the Bilibo is all about open ended play. It is a hat, a rocking chair, a shovel, a bucket, a box, a cradle, a hill, a tunnel, a cave, a drum, a hiding place. Or it's just a $28. piece of plastic, if you are a stodgy grown-up.
