I found out about this on TheAtlantic.com (original article) -- there is an interactive, 360-degree panorama of Mars made from assembled Curiosity Rover pictures, and when you access it on your phone, it uses the built-in accelerometer and compass to re-orient the image in real-time. That means as you sit in your desk chair and spin slowly around, your office turns into freaking Mars.
Freaking Mars.
The planet Mars.
