I told you that NBC Universal is decorating its “Green is Universal” eco-campaign this week with a strange but cool art project inside 30 Rock. An environmental muralist named Tom Deininger spent all afternoon yesterday inside Studio 8H–the home of Saturday Night Live–with 300-plus inner-city school kids and NBC staffers building a massive wall relief completely out of trash.

That’s right. 100% garbage. Used cue cards from Late Night with Jimmy Fallon. Old cassette tapes from NBC Sports. Junked CDs and DVDs.

I told you I’d share what these oddball artists created–and here you go.

The mega-mural is based on a photo called Aspen Groves by the late,  great Ansel Adams. NBCU hasn’t decided where they’ll put the mural on public display. But it’ll likely be a public school or community space somewhere in New York City. Any takers?
