Thanks, Gregg, it's kind of refreshing not to have to explain every single time why these kinds of threads should get everyone salivating. Just the fact it brought us Luke's work is plenty for me.
Now, a question about the glass, which is pretty cheap still to buy in a large enough piece. If you paint it underneath, it would still work . . . as a reflective surface. Some interesting ideas already a-swimmin' in my noggin'!
