Old Demos for Linux/GTK.

These may work if you have an older Linux system and don't want to add the recent versions of the shared libraries.  ATOMS and SHAPE require that your system have the Mesa OpenGL libraries, including OSMesa (the latest releases of ATOMS and SHAPE have these libraries statically linked).  Run

ldd wxAtoms

(or whatever the program executable file) from the console in the program directory to see what libraries are required.
