That's actually a pretty cool photo. I was staring at it, as my new background, and was thinking how amazing it is that their mutual gravitational influence is actually enough to keep the moon in its orbit. I guess I mean it's hard to tell just how massive yet, in contrast, how small something like the earth and moon are. That or it's the half bottle of beer I've had.

This is really cool, though I would like to see a version in higher resolution with some stars. Not oppressively bright stars, just a hint to remind you that there are billions of billions of violent, fiery balls of self-contained exploding gas out there...

Set it as my desktop background. Made me realize how dirty my monitor screen was. :)
