It does indeed. It's used in several games.

I completely forgot about Tetris and its nice visuals! Thanks, will see if I can use the library for ElCity.

I think misinterpreting the "el" as Spanish is fun. In that vein, your game could be called ElCiudad.

Somebody somewhere suggested doing a clone of Tropico called ElPresidente, which is even cooler.

Btw, Lars, you have endlessly more experience in Elisp than I do. Do you maybe have any ideas/directions on how to make the graphical mode look... A bit more decent and snappy?

Sorry, I don't know anything about Emacs graphics. Some people confuse me with larsi, but I'm not that guy.
