GameFrame is a collision detection framework for creating 2 dimensional sprite-based games which need to contain large numbers of axis aligned rectangular sprites. Alias Cummins is the original developer. Currently, some issues with the codebase are holding back the release - when these are taken care of, there will be an OS release.

It is likely that the development will be forked into a commerical and OS distribution, however efforts will be made to ensure compatability between both of these.
