Not much, I say. This USB critter is based on the namesake of the offbeat Seamour Sheep comic series, which follows the misadventures of Seamour and his anipal, Marty the Mole. Just plug him into your USB port, turn down the lights, and bask in the glow of electric sheep.

Seamour radiates an otherworldly green, presumably after he ate some radioactive waste, and Marty hit him up with the appropriate warning label in this particular episode.

There’s no word if Seamour actually will expose you to a high dose of radiation, or if he’s really powered by a bunch of green LEDs. Guess you’ll just have to find out for yourself. You can get your hands on this limited-edition (only 500 sheep) Seamour collectible over at Chicago’s (my hometown) awesome Rotofugi toy store for $69 USD.

Litrospheres are tiny self-luminous particles which can be injection molded or embedded into paints. Brightness is said to be about the same as that of a 20-watt light bulb, but I’d imagine that would depend on how much surface area is covered with the particles. The material is extremely cost-effective, covering an 8.5 x 11 surface for about 35 cents. The particles can even be customized to give off just about any light color. There’s a good description of how the technology works over on PESWiki.

MPK, the company that manufactures this glowing goodness expects Litrospheres to make their first appearance in safety gear, but I’d love to coat all kinds of surfaces with this stuff. Can you imagine how cool it would be to drive down the street in a luminescent car?
