For New Years Eve, Ch00f built these EL Wire shutter shades which use an analog circuit to react to sound like a VU meter. He’s posted full build details including schematics and tips for dealing with EL Wire, which he found to be the trickiest part of the project. [via Hack A Day]

    Instead of making a custom circuit, this can be done by using the
    inverter from one of those sound-activated “equalizer” T-shirts (aka
    T-qualizer). All you have to do is make a connector for the EL wire then
    connect it to the inverter. The inverter and panel without the T-shirt
    only cost about $7 at dealextreme.
