We've got threads for catsuit pics, funny pics, big-breast pics, wallpapers...but sometimes I run across pics that don't fit any of those categories. They may be pics of good-looking anime girls, neat maps, sleek aircraft, or whatever.
Since there is no real "matching" thread/topic for things like that, let's create a catch-all for pics that you find "neat" that doesn't fit one of the other categories.
I'll kick it off with a panoramic map of Mars. There is a larger, higher-res version available here if you want it.
