I have mine for about 4 months now, before that i used a set of stars which i used on my old forum as admin stars.
I decided to download the episode which i could capture this from and made 3 different avatars of it.
I also made this sometime ago which is use on the DiabloII.net forums.
For non Diablo people you can check this to understand whats so "special" about it.
