I did something similar in college. A company paid cash for installing software that displayed ads on the bottom of your monitor. It qualified your ad viewing activity based on mouse movement.
At night I would open the software, wrap my mouse cord around an oscillating desk fan, then go to bed. Earned myself $50/month
