what it is: stalk a shark
where i found it: a team of crazy scientists' website
This site details the goings on of a group of sharks and their human stalkers, who catch great whites (please see the pictures of the catching, what is wrong with these people?), tag them , name them and track them. You can pick a shark, such as Albert (a 9 foot great white from the southern African coast) and follow his travels, read about his biographical details and stay the hell away so he doesn't bite your ass. Leave a little time for this, the site gets increasingly engrossing as you explore it more.
