3D Medical Animation - What is Cancer?

I came across this video when researching cancer for my art. It's a good 101 basic visual overview of cancer on a cellular level. Isn't the inner workings of the body cool? No? Well, I guess I find it fascinating. It's a great reminder how everything we do and come into contact with affects us internally, to the very heart of us (a yoga reference). Seriously, even though yoga may be talking about a soul or some sort of other spiritual reference when referring to the heart, I always image my internal self and the good I'm doing for my self by practicing. Ok, I kinda got off on a yoga tangent. So just watch the minute video--It's educational.
