Hardware mostly. Unless you have something really cool to share.
Are you talking only PC/Mac/etc. tech or anything computerized? These new laser headlights that BMW has coming out are pretty damn impressive.
Heads up display on cars also infrared detectors to see people and animals in the dark to the side of the headlight beams.
@SquirrelEStuff I am thinking laptops, but anything cool is welcome. I love your link to the laser lights.
