Motion tracking stars

To extract binary from the filmed footage of the nights sky, I have motion tracked each individual star, mapping its progress on the X and Y co-ordinates to form a set of numerical data, displaying each stars movement per second. There are around fifteen stars in the filmed footage. These numbers can then be translated into binary. Each second of binary can be emitted from an emitter attached to the star, replacing it in its movement across the screen. This replaces the stars with violent eruptions of numbers, which will travel across the walls of the installation.
