Cross Views (wordpress.com)
Your camera has the ability to take three dimensional photos. Your screen has the ability to display three dimensional photos. You’ve probably never used either. This isn’t a hidden feature of some new phone hardware release, it’s a feature of your brain. All your brain needs to see in 3D is two pictures, and you can trick your brain into seeing 3D on a flat screen using just your eye muscles. I will teach you how.
