Christmas Lash-up, Colour-Changing Bauble

// Code for Christmass baubles. Takes the time of day from the particle cloud and maps the colour
// channels R, G & B with hours, minutes and seconds. This means the baubles is always showing a 
// slightly different color, with a significant change at the top of the hour.
