MAKE Contributing Editor Bill Gurstelle appears to be having a blast guest blogging on Boing Boing. I can’t keep up with all of his post, he’s so prolific. The first image above is from a post on a tree grown into a garden chair. I’ve always been fascinated by pleaching and other forms of shaping living trees. The other two pics are from a post on a mega potato cannon built by Christian Ristau, who built the absolutely stunning giant pneumatically-powered Hand of Man sculpture at Maker Faire.
