I have now updated my RGB Clock on to github: https://github.com/smartroad/RGB-Clock
There is the beginnings of a Wiki which currently explains how to use the clock.
Eventually I want to add more functions, settable display timer to be able to select times to turn off the display (over night or when no one is in the office). I might add date functions (currently it gets set to 1-1-2000 when setting clock as it isn’t used) - which may include an additional smaller display.
