As a teenager I owned an Amiga 500 – that’s actually how I started (seriously) programming. Oh, the Motorola 68000 CPU was just great to write code on.
One of the neat things about the Amiga community were the “demos” that would come out. Demos are like a music video for your computer with emphasis on creating real-time graphic effects.
They were all about pushing the boundaries of what the architecture could achieve – quite a lot like the Excel community really.
One of the demos that really stuck in my head was a fractal landscape / terrain generator. I was fascinated that a computer could draw realistic mountains.
I’ve always wanted to make one – just for fun – so recently I set about learning how.
It came as a surprise when I discovered that a terrain generator could be developed using only worksheet functions and a Surface Chart.
Here is a sample picture. It’s actually a Surface Chart! Every time you press F9 a new picture is generated.
