Folding proteins

I have to say, this really caught my attention: http://fold.it

It's called Foldit, a neat little program/game that allows you to fold proteins for fun, while at the same time contributing to science. It's also no trivial task, since not only do you need to know some basics of protein structure (i.e. intermolecular forces such as hydrogen bonds and dispersion forces etc.), you have to be creative and have a knack for 3D shapes. (You'll have to register an account to play it, but it's free and only requires you to pick a nickname, a password, and an email.)

Basically, the interface is really simple that it shouldn't take a long time to get used to, and it's not all the overwhelming either. Just follow your way through the tutorial, learn some basic terminology and you are ready to go and do real challenges, and don't forget - it's a game that helps biologists study proteins!
