@Eugen Mezei
Last I heard, he got himself total exclusive use of Vantanablack, despite the fact that it was actually created for scientific purposes - thus denying its use to both the scientific community and every other creative on the planet.
When another creator came out with the "Pinkest Pink" (someone Semple? Stuart Semple? Anyway...) that creator decided that anyone can buy and use his PINK pigment, bar Kapoor. Nor could anyone else supply him with it. Naturally, Kapoor acquired some and flaunted it with an image of the pigment on his middle finger.
It's partly incredibly petty, but also quite telling about Kapoor as a human being to have deprived every other person from using the "blackest black" pigment.
It's not as though he was even it's creator.
That's all I know of him - not his artwork, just that he's an ass (the Americanism seems more apt in his case).
Of course, that's merely my opinion and I'd forgotten all about him until seeing the link to Black 3.0.
