iAttractor is an iPhone application allowing you to generate dynamic three-dimensional Attractor forms you can navigate and alter. An attractor is a term used to describe a set to which a dynamical system evolves after a long enough time. Points that get close enough to the attractor remain close even if slightly disturbed. Geometrically, an attractor can be a point, a curve, a manifold, or even a complicated set with a fractal structure known as a strange attractor. Describing the attractors of chaotic dynamical systems has been one of the achievements of chaos theory.
