3D Slicer - http://www.slicer.org/ - gives you detailed 3D models for the brain generated from CT scans. You can use it to reconstruct other organs as well.
There's an app for that! search for "3D Brain" (Cold Spring Harbor Laboratory) on your device. Also available online:

I've never seen anything like this --- an accurate 3D model of a brain, which you can click and drag to rotate. This has a lot of educational value. (Apparently, static 2D images of the brain on Wikipedia et al don't really give you a good "volumetric sense" of what the brain looks like.)
My only wish is to be able to "highlight" the various structures of the brain, e.g., the Hippocampus, to know where they're located / how big they are in relation to the whole brain.
Bravo. Wonderful work.
