Yes, I've seen one in an organ.

Wow.
This sounds totally interesting to me.
You see, I'm a Leslie fanatic, I even used to dream about it,
dream about building one. I was able to quit the nightmares
after buying my 2nd.
Then I started dreaming about miniaturerizing it.
Been experimenting with coils on motors but that only gave me
tremelo and motor hum. Got rid of the hum by moving the motor
away, but then the device got bigger due to a transport band.
So far I've never heard a device or ProTools plug in that does
the leslie effect enough for me, exept a tweaked dunlop Rotovibe.
I could buy one of those once, but I couln't as it needed a repair
first and then they never managed....
I do not feel like building one, as I saw it is has a *lot* of parts.

And I still feel like building semi mechanic electronic variant.
Any suggestions on the subject are welcome.
The device should do tremelo, vibrato and timbre changes in some pattern.
My guess a real leslie is a lot complexer then a sine, due to all the
refections
in the room. A complex LFO might be sollution #1.
