I'm developing open source software for procedural modelling of 3d environments on my free time. This is something that I really enjoy doing and I have big plans for this project which I called pagoda.
Procedural modelling has been a passion for me since 2012 when I started my PhD. However, I now have a boring 9 to 5 job as a C++ developer in a completely unrelated area and this pet project of mine is what's keeping me a motivated programmer.
Have a look around pagoda, and if you like what you see or if you would want to see some big, shiny, new feature developed just for you, consider dropping me a line and buying me a coffee.
