Python

I am aware that to properly realise the work that I am proposing, it will require creating a software system (in code) that will enable the video tracking of the viewer's motion to be translated into the motion of the coloured dots on the screen.  However my knowledge of coding and software development is non-existent at the moment so I thought it might be an idea to learn a bit about coding and to try (at least) to create the random motion of the movement of the coloured dots on screen. Fortunately I came across magazine Rasperberry Pi that actually runs through the whole procedure of doing this in python.

The youtube video below also explains how to do this on my macbook.
