For those that attended my last evening presentation about F# at Ronua Roadshow in Timisoara (but not only), here is the demo I’ve shown, and one that I planned to show but didn’t due to lack of time. The purpose of these demos was to shown simple Windows Forms applications written in F#.

**Mandelbrot Fractal**

A Mandelbrot set is a set of points in the complex plane, whose boundary forms a fractal. The fractal, known as Mandelbrot fractal, is obtain by associating a color with each point in the complex plane (or rather a subset of it). The color is chosen based on the result of computing the value of the complex quadratic polynomial Z(n+1) = Z(n)^2 + c for a number of iterations (100, 200, etc.). You can read more about it on Wikipedia.

The program that I shown exhibits traits of both functional (for computing the fractal) and object oriented (for displaying the fractal) paradigms. It is a variation of the program available here, for which I kept the functional part (computing the Mandelbrot set is not very fast, I must warn you), but redone the user interface part. You can use the mouse to drag the fractal and the wheel to zoom in and out.

You can download it from here.

**Game of Life**

I blogged about this two years ago, when F# was still far from a final release. In the meantime, syntax has changed, classes have changed, so if you try to run that implementation of mine you’ll run into some errors. I have updated the code to run correctly with Visual Studio 2010.

You can download it from here.
