If you could make them small enough I have about several hundred and something animated things you can use (like those on my signature and my user avatar - including those extremely visually stimulating ones I'm not allowed to have on here 'cause they might make you go into convulsions [like that one guy who went out watching that Lil' John music video "Snap Yo' Fingers"])...

I put half of them in a Demonoid torrent you can go download:
