Welcome, Chatoyant. Your avatar looks like a lovely butterfly to me.
Piffka -- here's the source of my avatar:

I got it from A2K's choices and had no idea I was a logo until I just did a google search. I still think it's cute, however, and will continue to use it until I figure out how to shrink my own photos (I've tried with minimal success) and probably beyond that because I now recognize myself quickly while scrolling through threads.
And with that in mind, jespah, it would make things a wee bit more difficult if we were sharing our avatars with others on the same threads. Not impossible, just more difficult.
