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 [fraser.name]. 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.
Using touch as well as the third dimension to explore 3D data is an interesting avenue, as alternative interfaces need to be explored as much as representation.
