Notepad glitch

Notepad has a strange glitch with some combinations of words. It happens when you open notepad, type in certain phrases, save the file, close and open the file, and the document is magically changed. This got popular with a certain conspiracy theory phrase of "bush hid the facts", making it appear that your operating system is keeping you from your freedom of speech. The funny thing though is that it also changes phrases like "bill fed the goats" and "hhhh hhh hhh hhhhh". It's some sort of Unicode error with 4, 3, 3, and 5 letter words seperated by spaces. The system apparently detects some combinations as unreadable characters.

Play movies in MSPaint

You have no control of the movie ofcourse, but it's still pretty amusing.

Easter eggs

A virtual Easter egg is an intentional hidden message or feature in an object such as a movie, book, CD, DVD, computer program, or video game. The term draws a parallel with the custom of the Easter egg hunt observed in many western nations. In computer programming, the underlying motivation is often to put an individual, almost artistic touch on an intellectual product which is by its nature standardised and functional.
