If I can just correct this... space is void and there is no matter, so there is
no IOR, but there is in the air.. the air's IOR is ~1 and so the light passing
from air to space will be refracted with an indice of 1, 0 means no refraction
(ie: passing from space to space), common glass is at 2.2 i think... And again,
look at the glass on earth, it looks nice, look at it in space and it looks
different, because the IOR passes from 1 to 2.2 and in space from 0 to 2.2...
A negative IOR should simply result in the opposite effect, thus making a
magnifying-glass(?) into a fisheye-lens and making a fisheye-lens into a
magnifier...
Something pretty cool about IOR is when it's animated, ie relative to the clock,
that gives a very nice effect!
Just my two cents! ;)
