NASA

I was directed at some point to NASA's image-of-the-day archives. I went back to them last night, and... there are some incredibly gorgeous things. Some would make great YW icon bases, and most are freely available for use.

(One of the few listed with actual copyright is a collage that would be absolutely perfect for a "myriad worlds" icon, although where you'd put any text is beyond me. Sigh. Might not look as good brought down to size, though; I'm not sure.)

Somebody who does icons should go look?
