I just found that this morning. If you have 15 minutes, you have to watch these videos. They are really fun (are they?):
Enjoy! I did (partly)
I am not sure but where is the fun part? These videos just make me wonder and question, how many private information Google has for so many people.
The interesting part was when "Double Click" jumped in and started to collect the information.
It's scary, people should understand by now that there is no complete anonymity in Internet world.
