What a thread this has turned out to be, eh?
Since Marc posted a simple glass shader a few days ago we've; played with our balls, mixed them with other user's, discovered some bugs(crabs, perhaps?), found multiple different glass techniques, cast a few shadows, removed our in-sides, inverted our indices and now we've opened a portal! Bravo! 5+.
It's difficult for the eyes to decipher, looking at these inverted indices, don't you think? Very strange.
The highlights are especially difficult to control here, see the squared AA blooming?
Cool 'portal', though!
Did I mention I found another grey hair in my beard? It was reflecting a strange light in the mirror!
Oh and, yes: Marc, you
have been well-and-truly 'JACKED, man! Sorry!
EDIT:
HAHAAA! HE SAID BALL PARK! HAHAAA!
