First off, great site! Very fun and easy to use.

I created a version of Chua's chaotic circuit. You can check it out here:

There are many variations of Chua's circuit. The ones I have created are based on schematics from these sites:

Chua's circuit produces voltage oscillations across the two capacitors (C1 and C2) and a current oscillation through the inductor. The oscillations persist in the circuit even though all components are powered at DC.

In order to visualize the double scroll attractor you need to be able to plot the voltages against each other, like you would on an oscilloscope in XY mode. Are there plans to add this functionality?

Unfortunately, I have not been able to reproduce the characteristic behavior of the circuit using the time domain simulation. Is the numerical integrator symplectic? If not the oscillations will either die out or diverge.

If you interested in efficient and fast simulations of chaotic circuit , I suggest to give a look here: https://plus.google.com/photos/118285010585894969594/albums/5726003292402895713/5726020154806136434 and here: https://plus.google.com/photos/118285010585894969594/albums/5726003292402895713
