I have just uploaded a Harry Potter Tux, don't know if anyone is interested in it or not. If so hopefully it will show up in the list of Tux's soon.
Comments are appreciated he is the first Tux I have created. I followed the G2 tutorial and then added the rest.
I didn't realize this would have a bblack box on it, but if you click to enlarge it shows up right with a white background. The file is a png so its transparent.
