I've gotten a ton of feedback on my avatar, some of it critical.
The main complaints were the audio which I turned off the first day it was up and the generally creepy nature of the thing which I am not going to change right now because I like it.
The audio is back, but this time with a play button. If you want to hear the avatar speak, hit the play button.
I've also figured out how to change the background which reflects the fact that I am in Portland Oregon today.
I intend to keep playing with this thing and hopefully putting it elsewhere on the web like my myspace page, my last.fm page, my linked in page, etc. I'll let you know how it goes.
