Since I'm on a kick lately of cool images and such...
A while back, I blogged about a site with great panoramas of the Moon. Silly me, I should have mentioned Mike Constantine's Moon Pans website. If you have Quicktime installed, you can sweep back and forth on images, going around 360 degrees. It's not precisely like being there (you can, for example, do this feat in your underwear which is not recommended on the lunar surface), but it's still pretty cool.
