Christian took us to see the Light Vests at the Cyberdog store in London today. They’re really neat. The basic design is a black shirt with a postcard-sized passive-matrix display velcroed on the front. They show various looping animations in all flavors of psychedelia. The high-end model titled “Light Red Alert Vest” in the online store (unfortunately made with Flash so I can’t link to it directly) allows you to type in a custom message to a scrolling LED display (think Joi’s hecklebot). The designer calls himself Lightmaster. He offered to make a custom one for me, complete with PC software to personalize it. With an 802.11 radio it could, for instance, display images going by on the wireless network Etherpeg-style.
