Lorenz Attractor -- A chaotic 3-dimensional structure related to a set of three nonlinear differential equations associated with fluid dynamics. Plus it's cool to watch. This is a minor tweak of Canthier's excellent 3D version. This one lets you change Rayleigh and Prandtl numbers (check out the Wikipedia entry for Lorenz Attractor for a good summary of what these numbers are). The Scale variable can be used to zoom in or out during drawing. The Rotation can be changed, as can the timestep between points. I've changed it so it plots points, rather than drawing lines. This helps reduce problems with some combinations of parameters and high timesteps.

Mine looks like a new galaxy!
cool
rofl too bad scratch doesnt have a z angle, that would make 3d ez, oh well, off to make the solar system!
Very nicely done! Too bad Scratch can't handle Arrays.
Cool project!!!!!! P.S. Please come and look at my projects.
It shouldn't be too hard. I will take a look at it soon.
Canthiar: Good idea. I haven't fully digested your tranformation matrices; maybe you could take a shot at that...
nice!
Currently the rotation variable rotates around Y. It might be good to add another rotation slider that rotates around X.
