USB LED Light Tube Speaker is Like Bad Sci-Fi Prop For Your DeskThis 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]
