The human body is incredible. One of the things that we all enjoy are our joints (unless you have joint problems, then you might not like them as much). Their motion is elegant and beautiful, but it's hidden beneath a lot of other tissue rendering them invisible to the naked eye.

X-rays are one of the great inventions of modern medicine. For the first time, they allowed us to peer into the human body (noninvasively). These images are usually static, but Cameron Drake has taken it to the next level. With the help of Dr. Noah Weiss, they created a little video for us showing joints in motion as seen by X-rays. You can learn more about the project and how they accomplished this on Drake's blog, but without further adieu, here are the results.
