Vivace is a rudimentary Allegro 4.9.x wrapper for C#. The last time I updated it was around Allegro 4.9.2x, so it's not quite relevant (or ready) for Allegro 5.0.0. In any case, the wrapper follows OOP paradigms and C# style guides, so it blends in easily with the general framework of C# libraries. You can download it here.
While not ready for release, Brightside is (at the moment) a relatively decent OpenGL vector image library that uses the stencil buffer in order to render the vector data. As time progresses, it will become a game framework—dependant on Lua, Allegro, and OpenGL—that is used in yet another project: a tiny tale following the brave conquest of two little, but heroic, fellows. In the mean time, you can taste the latest version of it by checking out the Games section.
There are only a couple of projects, one of which is available for public consumption. However, do not despair. Soon there may be a Pokemon Battle Revolution model viewer, if I get around to finishing it and polishing it up for release (the model format is tricky!). In any case, there will eventually be more projects as I get around to making them. Until then, see ya!
