Even the title is a puzzleSourced
A painting called ○△□.
Or perhaps □△○.
Japanese monk-artist Sengai painted only a circle, triangle and square. The work is usually titled by reading the shapes right to left. But the ink's darkness has led some to suggest he drew left to right—and that the title should be reversed.
Three shapes,
two ways to read them.
