But seriously, nicely done. It's an image made into a sig, but it's done way better than I'm capable of. Speaking of which, I've been doing project work for easily impressed* group members, some of which I may post up here.
*I'm not kidding. Background + line of text (not even shaded or textured, I feel unclean) + single brush application and they went "wow that's really cool" in a completely non-sarcastic manner. Just for that I intend to knock their socks into the orbit of Saturn.
