Julia, Mandlebrot and Lyapunov

I stumbled on this site. Seems to be an attempt to explain chaos theory and more. Its put together by Glenn Elert. I am humbly impressed

and at the end of it there’s some cool programs so you can ‘make your own’ mandlebrot or julia or possibly even a lyapunov. Looks a bit like its for OSX only though - not sure about this.

If you haven’t, you really should check out Fractint. It is likely the sweetest free fractal program you’ll be able to find. Super fast and DOS.
