Roman Opałka was a French-born Polish painter who painted numbers. In 1965 he began painting a process of counting – from one to infinity. Starting in the top left-hand corner of the canvas and finishing in the bottom right-hand corner, the tiny numbers were painted in horizontal rows. As of July 2004, he had reached 5.5 million.

On August 6th 2011, Roman Opalka completed his work: “the finite defined by the nonfinite”

I think we may have to redefine “insanity”.
