Here’s a cool Eye Lamp that will open up as it sees human presence. (or animals too for that matter)
I do like it but it’s still a design, here’s a bunch more eye lamps you can buy though:
Eye Plasma Lamp is a good one for your livingroom, get bunch of these and turn all the lights off, that will be creepy!
Biker’s eye lamp is obviously a good choice for bikers who need that special, unique way to deter bad drivers.
