Bench that unfolds into a picnic table

I've made it a point not to sell anything on the Monongah High Alumni blog (I've even turned down offers to get paid for letting ads pop up here, because I want to keep everything free and un-cluttered with telemarketing for Monongah High alumni).

But I thought this bench that unfolds into a picnic table, and vice versa, was cool. Not promoting its sale, mind you; just fascinated by a mind that is this clever.
