Well, after some deep research, I decided to rename my Why ? 3 scene to Something Interesting 3, because it was interestiong to see the weird behavior of a laser with its velocity lower than +inf. this means this scene is the fourth in the "Something Interesting" series.
Well, remember my scene "Can someone name this thing" that I posted on April 24th ? Well, the name of this, uhh, weird shape came from NSP6213. It could be named differently, like the Contraprism (UnityDogGaming04), Sir Enigma the Perplexing (Ciurkitboy N) or the Twisted Sister, which was yours.
