Hey Poynt, plug all of those waveforms into a "rotator." The rotator is based on a quadrature oscillator that will rotate any waveform on an XY plane by an angle theta.
I am going to pull this from memory so here goes (might not be correct):
xprime = x(cos(theta)) + y(sin(theta))
yprime = x(sin(theta))  y(cos(theta))
So your input waveform could be one dimensional on the x or the y axis. Or, you could input two waveforms into the rotator, one on the x axis and the other on the y axis.
If theta is (omega*t), then your are continuously rotating the input waveform at 2piomega Hertz.
In plain English you are making a Super Spirograph that will produce all kinds of pretty patterns! lol They do it for laser shows all the time!
To do this circuit you need a nice quadrature oscillator with a variable frequency. Not so easy to do that the old fashioned analog way. Then the rest can be done with operational amplifiers and away you go! Plug the outputs in to the X and Y axes of your analog scope and see the show. Much better with a laser though! lol (I used to do laser light shows many many moons ago.) <<< OOPS! I also forgot that you need analog multiplier chips! >>>
Or, the whole thing could be whipped up in software quite easily. Nice sliders for your x, y, and omega values and look at the laser light show on your computer monitor.
