Fluxus ( http://www.pawfal.org/fluxus/ http://www.pawfal.org/fluxus/ ) is a scheme environment for live-coding graphics. Its a brilliant way to get started with games programming since you can modify code on the fly and see the results immediately. The underlying graphics engine is written in C++ so you don't lose much performance by choosing scheme.
