Neil Fraser, a software engineer at Google, took 9 carefully selected cross sections from a MRI scan and glued them on wooden blocks to create a 3D representative model. The result is a collection of 60 1-inch cubes, of wich 94 outside faces are simply varnished, and 266 internal faces feature a square slice of the MRI images. One can then "dig" into the brain to carve out custom shapes.
