Mexican artist Carlos Amorales' "Black Cloud" installation has traveled the world, appearing at Yvon Lambert gallery in 2007 and Espacio AV in 2009. It's made of thousands of black paper moths installed onto large, blank walls, making it an impressive sight from both near and far. His work takes days to install, but by the looks of it, it's entirely worth it.
