It's just a random stagger of tiles. It looks like there are three widths and they run: Large Medium Small Medium Large Medium Etc... It should be pretty easy to recreate.

I just ordered these ( http://www.amazon.com/Stainless-Steel-Tiles-Earthworks-Mosaic/dp/B001W85H98/ref=sr_1_1?ie=UTF8&s=miscellaneous&qid=1251070045&sr=8-1 ) from Builders Depot Direct through Amazon. I never heard of them before but going through Amazon means you get protection from Amazon in case they don't ship them, aren't as described, etc. I placed my order on Tuesday, they shipped on Wednesday, and received on Friday. $23 SF was half the price of any local store, none of which had stock. Get's installed this week. I was very pleased with the service. Good luck! Here is a link that might be useful: Stainless Steel tile through Amazon

Sharon kindly responded to my email request for information regarding her backsplash. I hope she won't mind if I share the information she provided. Sharon wrote, "My back splash tiles measure 5/8 x 5/16. I had a hard time measuring them, as they are quite small. I bought them at a granite/marble yard in Santa Monica, CA. I went there only one time, rode with my KD, and never went back. So, I don't even remember the name of the place. I looked this up on the internet, and I think it must have been on Lincoln St, as I see two places there. But, I can't tell you which one it was.." It's a lovely backsplash that complements the granite and doesn't fight with it; it's simple in design, but has lots of texture and interest; and something I don't think I would tire of. I've been without a backsplash for two years and hopefully I can find something that I like as much as I love Sharon's. Thank you again Sharon.

Looks like that tile is from Walker Zanger - the ‘cocoon mosaic’ (that pic is one on their site). http://www.walkerzanger.com/collections/products.php?view=mat&mat=Ceramic%20and%20Terracotta&coll=6th+Avenue here is the link to their authorized dealers in Canada http://www.walkerzanger.com/showroom-dealer/authorized-dealers-intl.php
