Accidentally I saw this site http://www.technoblogy.com/show?WNM

About the middle of the page, there is an example of a 3D rotating cube by a tiny Atmel chip on a OLED screen.

The code that rotates the cube is amazingly simple (comparing to a trig functions) and the algorithm is called Minsky circle algo.

Another link on Parallax site has a discussion about this topic https://forums.parallax.com/discussi...-sub-and-shift

Very interesting I may say.
