Going slightly off topic, an idea I'd like to try is a hexagonal drum pattern
sequencer. I got the idea from this:

I have no idea how it actually works, but from that patch I got thinking that
you could get multiple loops from the same pattern by moving time in different
directions across a (non rectangular) tesselated grid. 

If you see what I mean!??

I'm going to hack together a little script to do this, when/if I have time,
but feel free to take this idea further...
