I just stumbled on a link to the webpage of Isaiah Zagar on www.eco-artware.com
He's the guy who made the awesome sculpture/mosaic wall on South Street in Philly! He made it out of all kinds of stuff, old wall mirrors from a local gym, factory cast-off ceramic tiles, what a great reuse project. So any way here's the link to his page!
You can see a tiny bit of one of his mosaics in one of my pics from the Philly Greenfest in a past post.
