Mac fans! Where can I find the silicone Mac keyboard?

[ChickenScratch]

Hey Dudes. The topic says it all. I love the feel and everything else pretty much about the silicone keyboards for PCs but I can't seem to find one for Macs. If you know a web site where I could get one it would help me out a lot.

Something like this but the Apple version: http://www.usbgeek.com/prod_detail.php?prod_id=0194
