Artist Leandro Granato makes his tear ducts do art. The process starts with him squirting some paint up his nose, and then squirting it out through his eyes. The squirted paint falls on a canvas, and there you have it, art. Well he does arrange the canvas to have the paint squirt where he wants it, or at least the general area. To ensure that the squirting paint doesn’t damage his eyes, he created a “special formula” that goes easy on the eyeballs.
