5 hours worth of mouse activity on my computer at work, while putting the finishing touches on my MSc thesis research proposal, ethics application, and supporting documents. Dark spots are where the mouse stopped moving (the big blob must be where I was doing a bunch of typing or something). Lines are where the mouse moved. Light circles are clicks.
