So on the rare occasions when you venture out and get away from your mom’s attic, how do you geeks recognize each other? I’m guessing that one big giveaway would be this animated T-Shirt that plays old school Pong. It’s battery powered and it plays pong right on your chest.

Just make sure that you remove the battery before washing! Venture forth my geek friend and as you journey out into the world, you and your shirt will collect fellow nerds as if you were the Pied piper of Pong.

The Sari is a traditional piece of clothing originally worn by Indian women. The Google Sari is a designer’s attempt at being clever. Of course, if Google doesn’t appreciate it, your Sari may turn into a genuine sorry. It’s from designer Satya Paul, who showed the Google sari in one of his recent shows. Very clever. Or maybe not. I can’t decide. I can’t wait for his next attempt, which is probably iPhone inspired and called the Safari Sari or something. Maybe a see-through sari called Microsoft Touch. That one would be trouble.

Amanda Parkes’ dress will get a woman a ton of unwanted attention from geeks and nerds. That’s because it generates power when the wearer moves, using kinetic energy as a result of natural movements of the human body. Piezoelectric material around the joint areas, like the elbows and hips of the garment generate power in response to the mechanical stress. Electricity will be stored as voltage in a tiny centralized battery.

As far as style, it leaves something to be desired. Unless you’re auditioning for the latest Star Trek maybe. If an alien abducted you, I’m not sure if they would be impressed by this garment or just end our misery with a giant death ray.

You may now never have to worry about getting stabbed in the back literally as you walk down the street. A uniform manufacturer in Japan has reportedly developed a T-shirt which provides protection against knives.

The Daily Yomiuri reports these T-shirts are made from “slightly thick fibers that are more than three times as strong as cotton.” The strength of this shirt’s fiber reportedly makes it equal to that found in body armor. You can even toss it in the wash to get off the blood after you kick the ass of your would be attacker.

Turn signal gadgets for cyclists is nothing new, but you don’t often see them in clothing. Ph.D student Leah Buechley on the other hand, has designed several items of electronic clothing, but her signal jacket for cyclists really stands out.

LEDs are embedded in an arrow formation and they flash to indicate that you are about to turn left or right. That’s a good idea since it will warn motorists, and prevent you from becoming roadkill, which we know some rednecks eat. The LEDs are powered by the round device in the center of the jacket, which is a small, sewable computer chip that Leah also designed herself. She obviously needs to be working with clothing manufacturers.

This Video Vest screen certainly gets your attention. Why carry a boring cardboard sign, when you can get your message across with video, like a picket line for instance or to advertise your business. The Vest actually plays full-motion video with stereo sound so that you have a portable video display anywhere you want.

Apparently regular Joes like me and you can’t buy one due to the vest’s high cost and limited manufacturing, but you can rent one for live events and such. That really sucks because my thinking was that we could put some flat chested girls in this vest and give them a larger rack via video. It would have been my gift to them. I’m a giver.
