Life can sure be confusing for a teenager in this fast-paced techno-world we live in. Without the proper guidance, a kid could find himself unplugging someone's life support, or going to jail for borrowing the neighbor's WiFi. Hell, if old man General Tommy Franks (retired) has his way you won't even be able to hang out behind the Safeway and enjoy a six pack with your fellow juvenile delinquents without being tracked via GPS! So it warms our hearts when we do hear of a youngster that's bucked the odds and done something constructive. For example, a 13-year-old named David Baker has received a patent for his Light Beam Delivery System, a pico projector that fits in a pen casing, and works by combining three RGB lasers with an optics assembly that creates a light ray that is then shined through a rotating disk to the screen. "When the light goes through the lenses," he explains, "they take each light pixel and shine it onto a screen or wall. The lenses run back and forth until it fills the screen. This process repeats 30 times per second to make it appear as though you're looking at a solid image and not a series of pixels, and you have the image projected." And where did he find the inspiration for all of this? "I was sitting in church thinking about how to make projectors easier to handle and I just thought of it," he says. Here's to daydreaming during mass!
