I have delveloped a graphic library for Windows that allows users to program graphical applications, simple animatios, simulations and simple games, using plain C in a console only programming environment. It works with Windows gcc environments and it has been developed using MinGW. I have created it as a C programming teaching tool, but I am glad to share it with the comunity in the case you find it useful.
You can find all the necessary information on http://mermaja.act.uji.es/docencia/mgsLib
Thank you for your attention, any comment will be welcome.
