[Alex] sent in his clone of [Crispin Jones]’ tengu. The tengu is essentially a funky visual sound meter that looks like it’s lip syncing. [Alex]’s version is built around an ATMega48 microcontroller, an electric mic with a LM386 audio circuit and the required LED matrix display. There’s an example tengu video here – but I’m not sure what to say about the song in the demo. It’s not dependent on USB – it actually works better with the clean power provided by batteries anyway.
