Interesting.  That could be quite useful in the right situations.

On a related note, its also possible to make objects that do not register 
with the human eye.  A few years back, Games magazine (covers mostly puzzles 
and similar stuff, not vidoe games) had an article on a sphere shaped puzzle 
that could be taken apart and reassembled.  The trick was that the material 
the sphere was made out of made the sphere completely invisible to the human 
eye when the sphere was properly assembled (i.e. the refraction you see in 
glass and other transparent objects didn't exist).
 
This obviously caused a few problems when the people who designed the thing 
had an accident at the first convention they attended, and a few of the 
spheres slipped out of their boxes and rolled across the floor...
