You may have heard that artist Anish Kapoor has an exclusive license to produce art using Vantablack, a pigment made from carbon nanotubes that absorbs up to 99.96% of visible light. Covering an object with Vantablack makes it look like the object, and everything behind it, has been removed from the universe.
Artists who are not Anish Kapoor are understandably upset that Kapoor has a lock on Vantablack. Many people have tried to create pigments as dark as Vantablack, and the person with the most success so far is Stuart Semple. He created Black 2.0 a few years ago, and now he is Kickstarted a new formulation, Black 3.0, which absorbs between 98 and 99% of visible light.
The Kickstarter includes the following caution: "By backing this project you confirm that you are not Anish Kapoor, you are in no way affiliated to Anish Kapoor, you are not backing this on behalf of Anish Kapoor or an associate of Anish Kapoor. To the best of your knowledge, information and belief this material will not make its way into the hands of Anish Kapoor."
