I searched the Web, but the most I was able to find was 180x180 pixels. I'm looking for a ajax loader .gif animation that is at least 400x400 pixels. File size is not very important, it's for intranet application.
UPDATE: solution must be free as in beer. I don't own a copy of Photoshop, for example.
With Photoshop and a little bit more time investment, you can create one of any size and quality with this tutorial:

(Sklivvz posted this next one almost the same time I added it via an edit...)
Make one online in seconds (doesn't seem to have 400x400, but there are a range of sizes and styles):
http://www.ajaxload.info/ lets you create your own ajax loader, including some large ones.
Technically this is a correct answer:
I will post more images in this answer as (and if) I find them.
How about finding one as big as possible and scaling it. Could be that you'll find one that will work. There's always GIMP if you need to make your own.
