The reason is, oh my god, you are the first who test my code.

When I started this project, I made demos and some documentation, but
I stopped maintaining them because nobody was interested. Makefiles
compile OpenGL and SDL bindings, but now I use Figl and compilation is
not needed. The error with set-gl-hint comes because I have a figl
version with some improvements. I've sent patches to figl maintainers.

Currently, Gacela is in a very unstable state. Demos, for example, use
an old version with a more OOP style, because when I wrote them I was
beginning to understand Lisp and functional programming. But actually
I'm reestructuring all the code looking for a more elegant, beatiful,
functional style.

Yes, your style is more callback style. I personally prefer polling
because then I can read the code sequentially. But it's a personal

For the moment, no. But I have a lot of papers :-)
