Build a chair- out of grass

I just saw this the other day on Kanye West's blog. This lawnmower (MUWI) cuts grass into little disks or balls that you can then built something with. Maybe this is what we will have to use when all of the trees get get cut own and we can't make furniture with wood. This is also seen now in some cars that can run on gas full of vegetable oil. I hope to own this awesome invention one day so that I am prepared when some of our natural resources run out.
