This is a very simple Java programme I wrote for my extended project in maths because I couldn't find any programme that does this. It plots a two-dimensional function of the type f(x,y)=z using a colour code (high values have a brighter colour than low values) and saves the result to an image. I used it for f(x,y)=sin(x2+y2), which looks pretty nice.
The settings in the code are explained through comments, you'll have to try different values for other functions than the one I just described, I just uploaded the code in case anyone can use it. Maybe I'll turn it into a real application and/or applet some time, too.
