Coolest thing i've built solo? I think it's my 3D snake multiplayer game.

It all started with a simple 2D snake game to teach programming basics at community college. Then i added a multiplayer mode based on a simple UDP implementation. Then i wondered how it would look ike in 3D and i had the idea to figure out how to implement a 3D engine by myself and i dove into the maths and wrote a simple 3D engine based on a windows forms picture box.
I showed the game to my colleagues and the loved it and we played it a lot.
So i added special mode boosters, and sound and map events and obervermode and observer polls.... you know it.

Here's a little collage of the journey...
