Thanks! Got it working with a few different formulas, and I'm able to search for attractors in Chaoscope and transfer the variables into the grasshopper script to generate the same system as in Chaoscope. Any idea how to generate a surface off of something like this??

well, I used vb.net for this...you could just as easily do it with hoopsnake though.  attractors are pretty easy to make, you just need to find a formula and series of coefficient values that give you the general form you want.  Basically, you cycle through a set number of XY points with a 2D attractor...the location of each new point relies on the location of the previous point being run through the formula.  A good formula is here:

I think I used something like 5000 points per iteration, and then just animated the slider on one of the coefficient values.

This is awesome...how do you go about telling grasshopper to generate an attractor like this??? I'd really like to use this for my design research in Studio if you could give me any advice.
