Here's another type of metal tile I was looking at yesterday. I really like the look on my computer monitor, but the true test would be seeing it in person. Also, at $8.45/tile it's definitely pricey.

I like the metal tiles pictured in the link you provided, although the jewel inlays, while pretty, are a bit too bright for my taste.

Here is a link that might be useful: Patina Tile

Ooooh, I like that. But you're right, that makes my current $16.40sf tile look like a bargain!
