Rover is right, mono is an excellent opensource .NET implementation. However I've read there are some legal ambiguities over its attempt to implement ASP.NET and the Windows.Forms as they are not part of the documented open standards core of .NET (such as C# and the System modules).

I had read this in a Linux Format Interview: the men of Mono however the snippet online doesn't contain the relevant parts.

Thanks, but it could be a while. Being honest my project is meant as an extension to Apophysis not a replacement. The idea was that you'd design your fractal in Apophysis as it is a really excellent tool for doing so (as is Fyre possibly, I hadn't heard of it before this so havn't tested it). Then you export the .flame file and load it into my app for rendering and output tweaking. At the end of the day though my renderer gets less and less special if you have enough RAM to throw at Apophysis as you just render a larger image and resize in any old app which will also get rid of the aliasing pretty well.

Also unfortunately I was overly ambitious with the project in the beginning, I made it completely modular so that people could rewrite the entire rendering process with plugins. I got it working but it feels a bit like a kludge, I'm sure all developers can empathize when have a program which works, but your still not happy with how it works.

I may yet go back to it, but my current project is happily occupying my time for the moment.

It looks like you can access the source through CVS on SourceForge :)
