I enjoy programming in C++, and also know C, Java, python, php and x86 asm.
The various projects that I have / am working on include (these are all just for fun and to explore the capabilities of different languages / frameworks):

• raytracer
• object oriented OS in C++
• 2d game engine
• CAS (computer algebra system) which incorporates elements of compilers / interpreters

I really enjoy contributing to http://latex.codecogs.com/png.download?%5cfrac%7bStack%7d%7bFlow%7d
