I'd like to have glitches like that.

No, actually that is a (tesselated) glass sphere
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..!!
