Ever needed a

Here’s a nice generator by the French team Country and Kath. It produces animated GIFs for a style and background color you select. You can download them, and they are Public Domain (at least that’s how I understand totally free for use).
I know I’m contradicting myself here:
Seriously, drop animated GIFs. They stink.
AJAX loading indicators may be the only valid excuse for using an animated GIF. And maybe writing a blog post about them.
