In 1987, Rey Hernandez was featured in the Guinness Book of World Records for painting the largest painting in the world.
Nine years later, Rey was the first artist to have a show at NASA in 1996. The show featured his unique spherical paintings called "Unispheres".
Here he is with one of his larger Unispheres. The quote above his head reads, "Where does the space around you end?"
