No, actually that is a (tesselated) glass sphere :D
I don't remember all the details - the picture is quite old - but it was a combination of mistakes: wrong uv coordinates for normal interpolation, missing normalization and a wrong fresnel term.

I guess I was trying to do conic rays.!!! Figured out finally the issue was caused by not doing a normalization of direction..!!

Fake vignetting gone south (pro tip: don't stare at it for too long, might cause headache/seizures)
