That bouncing ball, is from GLBoing.c (can be found in glfw), like here: https://github.com/g-truc/ogl-samples/blob/master/external/glfw-3.1.1/examples/boing.c

The bouncing ball is from the "Boing" demo, written in 1985 by two of the people who wrote much of the Amiga's OS. GLBoing is a clone of it from much later - at least 1992, what with that being the year the first version of OpenGL game out. The first 28 lines of your first link are a comment block saying just that.

  Must've forgotten about it really. Thanks! The commercial just reminded me when I was porting it to lua ages ago. (Never owned Amiga myself, but Apple ][)
