FRUITY FRACTAL FRIPPERY

by The Fractal Farm



Plunging straight in at the deep end, here are a couple of dubiously

technical and. extremely complicated progs from our chums down on The

Fractal Farm. And who are they? Well, there's Thomas George Amsler

Rushton (snigger) and Jonathan Scott, who both should really have been

concentrating on their uni exams rather than playing with their

Spectrums. Be grateful they didn't though. Their fractal research has

now progressed into the third dimension, giving us a 3D Mandelbrot

generator which you'll absolutely lurve.



It's Basic all the way, so there's no need to fiddle about with

hexloaders. Just hammer it in and ... eek! It wants you to type in

four numbers! Fear not though. These are the usual Mandelbrot

coordinates, so you could try -2, -2, 4, 50 or indeed -1.5, -.5, .5,

100. Or just about anything, in fact. The results will be impressive,

but they'll take absolutely ages to appear, so be patient.



Next on offer is a Henon Strange Attractor plotter. You'll probably be

wanting to know what a Henon Strange Attractor is, eh? Ah.



Well it says here that it forms an infinitely long line that never

crosses itself using the equations:

	xnew = y + 1 -1.4 x X x X

	ynew = 0.3 x X

which sounds fairly handy to me. You'll also be delighted to hear that

the program features a zoom mode, so pressing 1 while the program is

running will make a little box appear that can be moved around with

the cursor keys (using Shift for added speed), and pressing 0 will

plot the area zoomed in on. Space will start plotting from scratch.



Once again, the speed of the thing falls some way short of "lightning",

so you'll have to either compile it or be extraordinarily patient.
