Courtesy of Hybrid Medical Animations comes a high-tech "visual study/exploration of the body in motion." The goal of the animation was to create a realistic representation of x-rays, while also capturing the beauty of various yoga poses. Looks like they hit the mark on both accounts.
In creating this 3D animation, no x-rays were actually used. No one was exposed to radiation in any way, shape or form. It's all just animation -- sophisticated animation that somehow manages to show "proper bone densities and represent actual bone marrow inside each individual bone." If you practice yoga, you'll certainly recognize some of the poses in the clip.
