VRD nerd

Looks like some science nerds at the University of Washington’s Human Interface Technology Laboratory have hooked up a screenless heads-up display they call the virtual retinal display (VRD), which, unpleasurable as it sounds, fires laser-drawn images right into your eyeball off microscopic mirrors oscillating at incredibly high speeds. Intended for use with cellphones and other wireless devices, the upshot is that the picture has a theoretically infinite resolution, is vibrant, bright, and doesn’t require those silly little screens right up in your eye that use up way more power. But yeah, you end up with a laser beam in the retina. And the other downside? Well, duh, it only displays red (that is, until we get some miniaturized blue and green lasers).

ok, so quick show of hands... All those in favor of having a laser blasting into your eyeball raise one hand...
