If you do anything online, chances are your personal info is being mined somehow - maybe by advertisers, maybe by the NSA.

But what do you do if you want to keep your information private? One idea is simply not to be yourself.

Rachel Law is a recent graduate of Parsons Design School in New York, and she has created a game titled "Vortex" for her final grad school project. The game allows the user to find cookies, packets of data a computer uses to track one's online habits, and trade them in for others in order to create a new identity. For example, one could create the persona of a 35-year-old housewife, and be more likely to find baking advertisements pop up than a 20-year-old single male. 

Law says "players" can use Vortex to customize the ads they're shown, and she joins the show today to talk about her game.
