If you've got the Linux box - do you need to add the microcontroller? You
may be able to do it all via a little program driving the parallel port with
some decoders to drive multiple sequences.
In addition, one key factor will be how many leds you wish to drive and how
many different "chains" of them you wish to control independantly.
And no, I've never done anything like this - just speculation on my part.
