Viewing the photos sent back from NASA’s Mars Curiosity mobile science laboratory has been exciting over the last week, but here’s one with a twist… and a roll.

If you don't have any Finder windows open and want to switch to the Finder and open a window in one fell swoop, bring up the app switcher with Command-Tab and tab over to the Finder icon.
