South Korean company Iljin Display is working on miniscule LCD projectors that can be placed inside cell phones and digital cameras. The projectors will cast a seven inch, full color display onto walls, floors, and the backs of a large people on the bus. The technology for the projectors is currently as large as a pack of cigarettes, but the company aims to get it down to the size of a matchbox by the end of the year. Unfortunately, enlarging your contact list with a projector won't change the fact that you only have numbers for your mom and Dunkin Donuts. Also, it's been around a half an hour since you last talked to your mom, so you might want to give her a call.
