Dream is a cross-platform game engine focused on 2D vector graphics (OpenGL backend) and realistic physics. The aim is to create a 2D world supporting object movement and interaction based on realistic Newton physics (probably limited to solid polygonal shapes).

Dream is written in Python, with performance bottleneck parts subsequently moved to Pyrex/C code. Dream uses Pyrex, PyGame, PyOpenGL, and Numpy. It is designed to support networking.
