If you have a high-speed connection and many hours available to view hundreds of fractal animations, then this is the place to go:

It is also a place to go if you just need a few minutes away from your daily routine to see some fascinating videos.

There is also one, which is part of the "Universe" viddies, that took the better part of a full year to render on 3 systems, all running 24-hours a day, 7-days a week.  This is presented as the Deepest Mandelbrot Zoom Animation ever made.

Enjoy !!
