I really like what happens to the sound of those shift-register noise 
generators when you sweep the clock frequency.  It has a very pleasant, swirly 
phasing/flanging/filtersweep-like quality - but also really nothing like phasing, 
flanging, or filter sweeping.  I'm pretty sure that John Blacet's Dark Star 
Chaos module lets you do this, and provides a modulation input for this purpose 
(it uses the old TI SN76477 sound effect IC).  I tried this out when I was 
messing around with the TI IC, and was shocked at how cool it sounded, although the 
effective sweep range was not as wide as I would have preferred (using the 
chips internal noise clock).  Did you ever experiment with sweeping the clock 
frequency on your own shift register noise generator?
