Happy Halloween! Here’s a little project I’ve been working on for Halloween…
I’ve created a separate page with the details: it’s pretty rough right now, but I’ll try to tidy it up as time goes on. Feel free to mail me with any direct questions to serve as incentives to documenting the project better.
Cool! Would love to see a code listing, I’m curious how you got the flicker to not look too repetitive. Perhaps your PWM pattern is long enough that repetition isn’t noticeable?

Oops, guess I should’ve read a little closer. Neat trick with the LSFR, hadn’t seen that before. Where did your LED modules come from? Cree seems to make quite a variety.
I got them from Deal Extreme. Not sure what model precisely (Deal Extreme is pretty sloppy with their specs/IDS) but something like this one:
