MOTM

I'd like to have one of these myself and I plan to build one if Paul 
or someone else doesn't first :)
My plan is to use a wave table and some counters.  You'd shift the 
phase by adding or subtracting from the counter.  The counter would 
point to an address in the wavetable.  The rate of the counter would 
control the frequency and the offset of the counter would control 
the phase.
This is very similar to my idea for a Fourier series generator and 
also very much like Paul's forthcoming Cloud Generator.
I'm planning on getting a stooge panel for this in the next run 
although I haven't built the circuit yet.
