Screw Google Glass. What I want is to see the world slowed down, shot at 500 frames per second and played back at 24 frames per second whenever I want. Or see time-lapses by blinking twice and accelerating time. Example: This corgi.
Just imagine being able to watch anything in the real world and be able to instantly rewind and see it in slow motion. Seriously, I want this. Someone implant something in my brain asap.
