As an aside, has anyone noticed the distracting flickering of the background in the animated infographic? It looks like it is glitching, and I am assuming it is not intentional? Is it an effect of viewing it on an LCD screen?
it's gif dithering. The source is probably a video file and whatever graphics package they exported the gif from couldn't generate the exact shade from the given palette.
I noticed it too, on an LCD screen.
I noticed it as well. LVDS laptop LCD, Firefox/Xubuntu 15.04.
