I actually built a Daft Punk helmet a few years ago.
The lights were quite easy because - and here's the weird bit - I bought a gadget with LED lights that reacted, equalizer-style, to music. I think it was a coaster,
, but you can get the same tech wired in to T-shirts, desktop toys etc.
So there you go. Get yourself to any shop that sells lame executive toys and gadgets, and rip the guts out of that. No programming knowledge needed!
