I was particularly struck by the passing reference to the (unknown to me) International Klein Blue, a color made by and then patented by Yves Klein, a pure blue pigment suspended in clear resin, a color that cannot be experienced on a screen or page, but only by seeing the real thing. An experience that you have to HAVE in person, that cannot be approximated online. A bit of google and wiki later, I read the surreal ending to his life: "[Klein] suffered a first heart attack whilst watching the film Mondo Cane at the Cannes Film Festival[...] Two more heart attacks followed, the second of which killed him on 6 June 1962. His son, Yves, was born a few months later in Nice...[His son] grew up to study architecture, design, cybernetics theory of systems, and Fine Arts sculpture. He went on to create robotized sculptures." One thing leads to another and before I know it I have read a series of things that together induced the sensation of having experienced a moving art installation.
