Here is an interesting site detailing what I guess you'd call, well I dunno what.

Basically, a guy creates a tree out of plywood, and then chops it down, recycles it into a sheet of plywood and then returns it to Home Depot for a refund. Some kind of statement I guess.
Personally, I really like the tree he made, and it is a shame to chop it down after all that work.
