Chrome

Have you ever seen a car body shop, where they used to fix up those old cars that were in fender benders. They had huge vats of stuff they would dip the fender into, and it would come up looking all shiny. Was like liquid chrome. Bit like Terminator 2. Luckily cars don't often come into contact with liquid nitrogen, or all that shiny chrome would look rather messy shattered into a thousand pieces. Of course, cars don't come in chrome anymore, everything is plastic these days.

As you can see, this is exactly the same as the previous goblet. Except the material has had a single change made to it, adjusting the fresnel value, which varies how diffuse the reflection is. For this one, fresnel is set to zero, which gives it a mirror finish like the chrome on a brand new fender.

I haven't yet tried putting two mirrors facing each other to get that reflecting to infinity look. Or maybe several funhouse mirrors, curvy ones that distort your body to look like some weird clown with large feet and a huge 1-pack (only 5 short). Or maybe a spherical mirror to give that wide-angle lens look. Or sorts of fun ahead.
