alladvantage

I'm sure you're aware how much companies have been fighting over the Internet market and how valuable we as consumers are to them, we can get free computers, money and god knows what else if we just pay attention to them for a matter of seconds. 

A lot of these deals are for webmasters to have them promote another site or product, well you can also make money just by using your computer and having some ads displayed while you are on the Internet.  

Alladvantage is one such program.  It tracks whether or not you are active by mouse movement apparently, so you could "trick" it with a program like Fake Surfer which makes your computer/browser look active even when it isn't.  Of course that would violate the rules of the agreement you make, but it is an interesting idea, you could I guess be "active" while you are sleeping or away from your computer and be paid for it.

Oh, another thing about Alladvantage, if you sign people up under you, you get money for the time they spend online too, and the people under them and under them.. etc.
