When i saw the 60 degree light travelling thing, the first thing thought to myself was "I wonder if that fits into sine waves.." so opened up photoshop, grabbed an image of google, and plotted from 0 -> peak -> pi (180 degrees) and it definitely looks equilateral. I think this could have something to do with it, I'll leave it for those more interested to take it further.
