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.
