Here's a Codepen http://cdpn.io/CnwtL
I'm trying to mimic/improve the mouse move based scroll that you can find here: http://www.ciena.com/resources/posters/Packet-Optical-Convergence-Infographic.html (you have to click for the infographic to see what I'm talking about).
The problem right now is that when the mousemove event doesn't seem to be firing. Any idea why?
