What I do on Gaia
Animated GIFs:I've made a list of the animated GIFs found around Gaia in my List of Gaia’s Animated GIFs thread. The newest GIFs will probably be towards the end of the thread if you're looking for links to them. I haven't been good at keeping the first page updated, but others have been posting links to GIFs when they find them.
I sometimes edit the GIFs for fun, though I'm not very good about fulfilling requests anymore, so I don't want to make any promises if I'm asked. At this point, my art specialty is generally just doing various recolors of existing GIFs, or assembling the frames used in Flash Space walking animations (such as the walking animations of "I am" items) and turning them into GIFs.
