I'm sure there are folk on here who can easily do the sums and code for a Mandelbrot generator. I've used plenty of fractal progs but I'm crap at making that sort of thing, but I like to use a bit of bloodymindedness and I wanted to make one. Against this is the fact that the only computer language I ever knew is BASIC, which I messed about with on BBC micros years ago. But the interwebs has the goods! There's a free (trial) version of BBC Basic for Windows out there, and I stumbled across a printout of a Mandelbrot generator program from this old page. Yay, I now had the tricky part done (done for me, that is. Heh, I know the maths, just not how to implement it). It's not a great prog, but (after OCRing and correcting the code - I'll post it here if anyone's interested) it does give a result which is recognisably a Mandelbrot: So I tweaked the parameters and reset the page size (the prog was asking to be hacked) and got a thing that looks like this: which shows a bit more promise. More tweaking and finally beginning to understand what the hell I'm doing and getting some idea of what imaginary, real and complex numbers are, and I found I could zoom in and navigate a bit about the Mandelbrot set. The prog still needs working on before it's an easy tool rather than a lot of tweaking variables in the code, but there's stuff like this to be had, which sort of boggles my mind considering it's a very short and simple piece of code which does the work, and the trial version of basic is a very limited software environment (apologies for outsize images): So, erm ... just thought I'd share.
