I am a PhD student at NUI Galway in Ireland researching energy efficiency in
data centres. In the course of my early research I was writing some code to scan
a heat map of a data centre floor plan to identify hot and cold spots in the
room. The more I developed the code the more it began to look like a version of
the original pacman game. So, late one evening (as is often the case with
programmers) I decided to take the code further. Below is an interesting section
from the first evolution of the game which I have called Scanners - based on
what I was doing when I started writing the code.
