I recently watched a very interesting video describing how engineers created Vantablack, a carbon nanotube-based material that absorbs 99.96% of light and is renowned as the darkest material on earth. By reflecting almost no light, objects covered in Vantablack almost completely lose their sense of depth., as you can see in the image below.
Since its invention, Vantablack has been used in many pieces of art with the surrealist effect it brings to pieces. At the Pyeongchang olympics last year, artist Asif Khan created a pavilion using a Vantablack paint that looks like a galaxy of unknown depth, as you can see in the top image. I find this to be a very interesting intersection of art and engineering and highly recommend reading more about it here: https://qz.com/quartzy/1212647/a-vantablack-art-installation-in-pyeongchang-creates-a-stunning-visual-illusion/
