This is a cool little program that tracks your mouse movements http://iographica.com/ and creates an image file that shows where you’ve moved your mouse, and when you’ve paused in certain locations.
From their website: “IOGraph — is an application that turns mouse movements into a modern art. The idea is that you just run it and do your usual day stuff at the computer. Go back to IOGraph after a while and grab a nice picture of what you’ve done!”
Here’s a couple of examples of what 3d modelling a streetscape looks like when translated to mouse movements.
