You know, Bain, there's a reason why anyone who is actually good with sigs will only use one or two pictures for a signature.
It's damn near impossible to stuff a bunch of pictures into a signature and make it look good. There'll be no focus, no balance, and chances are parts would not match and it simply wouldn't look good.
And as Baka said, there is a file limit of 50kb. There's no way you could get an animation like that you want under the limit with it being 1) tiny and 2) pixelated and looking like shite because you had to cut down to 4 colors.
So yeah. If you think it's so easy, do it yourself. Your attitude has likely made it so that no one here will help you.
