Further explanation of Leanna's sculpture (and a cool book)

The book read by John Lithgow. Good advice, for anyone, of any age. If you don't already know it, this is an extrememly popular book to give as a present for graduates.
Around 2:35 you can see some of the structures Leanna's class used as inspiration for their sculptures. The whole class' sculptures were really neat. All twisty arches and houses on stilts and such. Hers actually looks much better in person than it does in the picture(I'm not sure why).
