Oh boy. Oh boy. The random generators in VCV are getting more and more numerous! I can’t be more happy!!
Well, shall we talk about Chua’s attractor or Hénon’s attractor, apart of course Rossler’s?
And, if we consider the general definition of “strange attractor” we can also include primitive fractals like the Cantor’s Dust (and I can hear echoes of another plugin, here…)
I know Cantor’s Dust is not an attractor in the rigorous sense but if you want I can give a mathematical explanation about that! 
Too bad, I cannot help at all in coding but about Math, that’s another matter. There, I can help!
So yeah, there are some strange attractors that can be implemented, if you want!
