The Lorenz attractor is a set of three differential equations that define a path in tridimentional space:
Given a 3D point in space (x,y,z) at time t0, you can calculate the next point t1 by using a numerical iterative method (such as Runge-Kutta). If you apply this again and again you can generate a set of points that can be rendered and animated.
So what about it? This path has a "butterfly" shape and exhibits chaotic properties, a small change in the initial point can lead to completely different (and apparently random) paths.
