Phun – 2d Physics sandbox

Phun is an educational tool used to enhance some physics concepts.  It was coded by Emil Ernerfeldt, a Computer Science student from Umeå University.

Phun was coded in C++ using OpenGL, GLEW, SDL (for window management), SDL_image (for reading images) and boost, including boost_filesystem. Everything was coded by Emil Ernerfeldt, including the physics engine and user interface.
