Meet Sengai's frog, Wei Moo. Sengai (1750-1837) was a Zen monk renown for lighthearted word + image ink paintings called "haiga." You might think of them as visual haiku, the idea being to see what isn't really being said because it can't be said. But, by looking carefully, you might have something like an "a-ha!" experience. The image is not an illustration of the words nor do the words explain the image. Together they form an aphoristic sketch, each dependent on the other.

When Sengai was accused of playing with the brush to laugh at human infirmities he retorted, "No, I do not. Every stroke of my brush is the overflow of my inmost heart." Exactly!
