That's really cool, Eric.  I wonder if you might have one additional  
i/o pin left to include a hard sync input?  I'm not even sure hard  
sync is possible with your wave generation technique, but if it is,  
it would be hella useful.

I would also love to see you try to make a low-frequency  
implementation of this for voltage-controlled digital LFO use.  What  
do you think?  How smooth would these waves look/sound at LFO rates?
