Ever since I saw Ghost In the Shell, I've wanted their techwear display technologies to be real.

Use cases I want:

• Adblock in real life-- replace billboards and other propoganda with pictures of cats.
• Anthropophobia filter-- replace strangers with dark coloured cylinders.
• Navigation HUD-- See a compass, my destination, and my buddies' location
• Tachikoma assistant-- sometimes annoying, but their help comes in clutch when you need it most
