I was going for a combination of arches, the letter A, and a lambda. Please excuse the black corners; the app is hosted at Google Apps, which seems to have munged the transparent color when I imported.
I don't really see the lambda, but I like the rest. Very dynamic and energetic, and it doesn't feel "forced" into a concept the way some of the other logos have.
Thanks for the kind words, although I also agree with the critique from eds. I do think that there's a core of a graphic design idea that's OK; someone with better artistic chops could probably improve on it. In my defense, I'll say that it scales down very nicely to a 16 x 16 icon, which is what I cared about most.
Actually, given Mr. Graham's artistic abilities, I'm surprised he hasn't thrown something out himself, just for fun.
