I have tried this several times, but this is the furthest I've gone ;-)

The original object has a glass texture.

testjunk_ab_0011, 30 slices, sphere with a smaller radius
testjunk_ab_0010, 80 slices, sphere
testjunk_ab_0009, 80 slices, blob

Create array +2, empty outside grid
Scan the object, initialize array element
Scan array, place object if at least 1 of 6 faces not defined (not inside)

Comments welcome:

The blob version looks good... whatever it is ;) Now, should you choose to do
so, use a pattern to scale &/| displace the spheres comprising the object. You
can make rust or some other type of surface damage that way. Might be difficult
hiding the underlying matrix, though.

Currently the blob sphere component is not scaled to match the non square 
grid. I would also like to add a slight randomnes. Higher counts get 
smoother, but longer parse times.

First on the todo list might be:
save to .inc file
use different x,y,z steps, for non square scans
have a mesh type output

Is there going to be an anaglyph version?

(I didn't see one for last month.)

Yes :-)
On something with more detail.

What if the spheres were placed randomly?

Or what if the sphere were placed in the more compact packing scheme ?
(of spheres around a sphere)
(instead of cube / square, use shifted planes of hexagons)
(There is two variants: ABA and ABCA)

I have added some randomness to the placement and strength of the blob
component. Next is to add some kind of save to file.

Some anti-aliasing would be interesting: smaller spheres where the sampled 
object only partially intersects your grid.

I can now save the result to a file.
I like the result on the text.
