Peter de Reuver created a Python script to generate 'attractor' type structures.
Inspired by the newsitem from Gamel I made a little add-on (formulacurves from Lorenz and Rossler attractors)..Just being a hobbyist it's not perfect, but you can generate nice curves with it (see example). Not all combinations of parameters will generate a "true curve". But just play around and i'm sure will get something nice!! Who does want to be attracted???
Happy Christmas to all!
