Thanks all

>hows about a quick synopsis on how you went about it... =)

Maybe but i wanna be mean for now and keep the method a secret. But no doubt i'll probably end up getting bored of working on the engine so i'll make it open source.

However, thats not gonna happen soon, (my getting bored) because I've just discovered a technique that might mean I can create a landscape with hills and stuff, instead of a flat plain

obviously it doesnt work right now, but hopefully this gives you an impression of what I mean.
