Project Euler [Oh, this isn't spam mail...]

This isn't a question. :-D. Anyways, there's a website that I came across which has kept me up past bedtime the past few nights. "Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems." http://projecteuler.net/index.php?section=problems Take a look. A fun thing to do when you're bored.
