ctalk
Object Oriented Language
...That means you can use Ctalk for GUI, network, client-server, and systems programs as well as traditional object oriented simulations, with all of the advantages of a true object oriented language, like class and method inheritance, and rapid prototyping. Ctalk includes a just-in-time compiler, a compact run-time library, and a developing set of X widgets and OpenGL classes to create desktop and 3-D modeling apps. Written for use with GNU GCC and LLVM, Ctalk supports a variety of UNIX, Linux, and MacOS systems, the X Window System, and libraries like the GNU readline library, and the Xft Type1, FreeType and TrueType font libraries.
