So, I was bored like I always am and decided to try something fun. So I downloaded a mouse path / heatmap program that keeps track of what your mouse movements and pauses look like and converts it to an image. Then I did several hours of BGs and exported the image and put it ontop of my UI. This is how it turned out. Feel free to try it yourselves with the following link.
I'd really love to see some other images of what peoples mouses do when they play WoW. I'd imagine it is vastly different than mine. Even more so if you are a button clicker.
I also find it weird that mine has so many perfectly straight lines. How could I drag my mouse in a perfect line and then somehow always manage to bring it back to the center of my character?
