David, Jim Muth said, "...the formula Z^2+C consists of two complex numbers which have four variables in all. Four variables define a space of four dimensions." Here's as much of one four-dimension fractal as can be seen. I've projected the 4D fractal object to 3D, then put a string of these 3D projections together into a pseudo-4D .gif animation. A different 3D portion of the 4 dimensional fractal object is shown in each frame in the animation: http://home.earthlink.net/~hallane/hals_fractals_n_photos/ - Hal Lane ######################### # hallane@earthlink.net # #########################
