Like the iPod ads? They do look rather cool don’t they. Anyway I came across a couple of interesting pages on how to do this. I have attempted to do it myself but my efforts aren’t great, if I get some more time I will try and do some better ones that are worthy of posting. Anyway here are some links, the first is a bit more basic [www.photoshopsupport.com] but the second [www.macmerc.com]is a bit more advanced and probably will get the best results.
