Conceptual Artist Roman Opalka, 79, Painted Numerals To Infinity

“Starting at the top left of a canvas measuring a little over four by six feet, and using acrylic paint, he used a fine brush (No. 0) to inscribe 20,000 to 30,000 white numerals … in neat rows that ended at the bottom right corner. Each succeeding canvas, or ‘detail’ as he called it, picked up where the previous one left off. As of July 2004, he had reached 5.5 million.”
