This transparent, glowing USB speaker is either missing one glowing arm to make it look like a flux capacitor, or has one arm too many to be the light on top of the TARDIS. It's weird. But if you're into EL-wire PC case modding, then I suppose this blue LED-lit USB speaker from Brando might be up your street. Measuring 5.9-inches long, it takes power from USB, has an audio-in socket and costs $22. [Brando]
For your desk? Considering most of our desks are bathed in fluorescent light all day long, I don't think this thing is very useful for that purpose. However, I do think it would be popular among the college kids who want to jam out in their "grow" closets.
