Some kind of rotary?

[BarryW]

I would absolutely love a good leslie/rotary pedal.  The DLS is great, and many use a simpler chorus pedal (Arion) to get the sound - but I would just love a good fast leslie sound.

I ran across this the other day too, Music From Outer Space has a really nice-sounding Stereo Auto Panner project:

It's a pretty complex build though, and seems like it would need a stereo amp setup to work.
