Gri is a language for scientific graphics programming. It is
script-based, not GUI-based. Some users view it as a sort of LaTeX
for scientific graphics. Users who climb a slight learning curve are
rewarded with considerable aesthetic power.
GSL is aimed at providing a tool for rapid graphical programming. GSL is an object-oriented script language with graphical support. Its goal is to provide an easy way to specify worlds and at the same time enable the coding of behaviours of those worlds.
