Blue Marble

Stuff like Blue Marble make me want to go work for nasa.

I'm a bit of a map nut and I found these composite satellite pictures to be quite cool. I grabbed the "topographic & bathymetric shading" one and with some resizing made it the background on my dual monitor setup at work. It wraps great, so the transition when in tile mode is seamless, which is great.

There's more interesting pictures to shake a stick at, so knock yourself out.
