@ryewoz... i used the duck that had been used in other dock icons and overlayed the 49ers logo. then i just painted on the shirt. mostly used photoshop for the whole thing. i'm a designer by trade, so it was pretty easy for me to get in there and make the changes i wanted :)

@horha12s... the duck is actually the mascot for adium, so i'd recommend getting in touch with them if you want to use the duck (or it's likeness) on your site.

thanks for the comments! :)
