Phaser is an intuitive program for graphically and numerically analyzing dynamical systems on a computer. Such systems include multi-dimensional Difference Equations, Iterated Function Systems, and Ordinary Differential Equations exhibiting bifurcation, periodic, equilibria, chaotic, and strange attraction behaviors. Phaser captures and manifests these dynamical phenomena with its powerful Views.
