So for the last hour I've been zooming in on fractals.  This Xaos program is pretty sweet.  Left click to zoom, p for random color scheme, and a digit for a different fractal (1 to jump back to default zoom of Mandelbrot).  If you go into Calculation > Iterations, and turn it up (mine is at 500) it'll let you zoom further.
