Very impressive work, d. fisher! I like the "wood grain" look of the pine one.

I gotta say though, a version made out of welded, ground, and polished stainless steel sheetmetal would be possibly even cooler.

On a side note, does anyone know how real diamonds are "cut" or polished? I'm just curious. Given they are one of the hardest substances known to man, I can't think of any known abraisives that could get the job done without wearing out at least as fast as the diamond being polished. Are they fractured in a controlled manner somehow?
