Imageshack deleted it, archive.org never stored it, Google Images returns nothing useful and neither of my computers has it. I'm going to look through my old backup DVDs when I get a free moment, but if any of you happen to know where I could find the avatar I would be grateful.

Also, I find it amusing that a Google Images search for Light Prognosticus returns a Youtube video of my avatar (with an ugly text banner across the front of it) before the LP itself.
