The first one is a really weird. Enjoy a roller coaster naked. This incredible experience took place in Thorpe Park (England) in order to enter in the Guinness book. People can do anything just for a record.

Case modding. Very original case moddding for a PC. I can't imagine how the car's owner would look like.

The last one is a Flash animation. Fucha fucha is a very basic animation but I can't see the point of it. What did the author wanted to tell us? I don't know.
