From the dust jacket...

Jimmy found a ball rolling on the ground. Isn't that strange without a hill around?

Hold onto your hats -- and your paper plates, masking tape and bobby pins -- and join Jimmy on his adventure through the whole world of the ball and the constantly changing 3-D shapes that are its parts.

In unconventional verse that makes leaps as surprising as the ball itself, Bradford Hansen-Smith will show you how to build from the whole into parts and open up a new way of looking at the world around you.
