Close, but not quite. PC-oriented in the sense of PC being "Personal
Computer, not the IBM PC. The magazine was Creative Computing, the July
1985 issue: "3D Fractals", by Michiel van de Panne. The program gave
BASIC listings for a TRS-80 Model I/III/4 with CGP-115 plotter, a
Macintosh, and an Apple II. The author credits the technique to an
article in the September 1984 issue of Scientific American, who in
turn credit it to Benoit Mandelbrot.
