Double Dutch

Theo van Doesburg was a Dutch artist who, while not as famous today as his friend and fellow Dutch artist Piet Mondrian, also made paintings that featured strong black horizontal and vertical lines defining rectangles of primary pigment. They agreed that this was the best way to make art. Then Doesburg suggested that diagonal lines might be cool too, and Mondrian said nope just horizontal and vertical, and they stopped talking to each other for five years. Which might seem silly at first but the more I think about it the more I wish I cared about anything that much.
