When I'm curious, I just ask.
Mine means I like playing with photoshop and painter and I originally chose this handle to go along with a favorite photo of a lion I used to use as an avatar. I've changed from time to time, but always keep the lion in some form.
Here's the previous one I used as well as the original version of Lindsey Lacey's avatar (I didn't take the original photo, just did the post processing on this one). But this is the way I saw her after we met. This lead to her allowing me to photograph her many times which has been an absolute blast!
