Nice... I like the talking heads. Specially the second one, because it gives a more world-wide look of donationcoder.com.
I also support the $ issue, if it's to be there, it should be "disguised".
I think the way wreklessxx made the cut-out part looks better, though.
Oh... I've just noticed that the first one you submited had cody on the background!!
I wonder how the keys one would look with the 0101 on the background..
