Both of us in our team are very keen on privacy, we like to talk about it, write about it and hack around it.
Cookie Monster is essentially a Google Chrome extension that let's us know how many 'cookies' are out there watching us behind the browser. The number of trackers is then sent to Arduino that converts the number of cookies into air which is then pumped into a cookie monster balloon. Simple as that.
We learned that dictonary.com uses 60+ trackers\cookies.
What's next for Cookie Monster?
Forever eating cookies.
