Hmm...well, you know what a wormhole is? And I'm not talking about the 
kind made by slimy burrowing invertebrates...I mean the relative to 
black holes.
The portal pigment basically links one area of space to another...kind 
of a "magic mirror" effect. You can see into a different area by looking 
into the portal, and you can set things up so you see the portal itself 
through the portal, producing a "hall of mirrors" effect. However, this 
is done by changing the color of a pigment to what would be visible 
through that point on the portal.

You will also be able to set it up to act like a video monitor showing 
output from a camera, a less interesting but probably more practical 
application.

If you have trouble visualizing it, don't worry...it gives me headaches, 
and I'm still not quite sure why type 0 works. Or sure that it does.
