You answered it, Croquet. But you will have to implement the object 
structure for the a voxel space first. A toolbox of methods to fill a 
space, give voxels behavior through calculations or representations.

I would class this as less relevant at first, finally it will be 
crucial. So don't bother about it's memory footprint now (up to 500MB, 
a few gigabytes an the next year). But when you now how you want things 
represented and actually used it, start thinking about efficient 
storage only
A general Morp(Squeak) hand Croquet approach to base your first mental 
model and first demo on.

There has been some discussion before, i'll start looking through the 
180MB maillist archive.
I remember that there is no real issue here.

A general Morph(Squeak) and Croquet (Squeak) approach to base your 
first mental model and first demo on.
Croquet is the obvious place to visualize voxel spaces.
