Reminiscing over one of my favourite passages from Anathem, I've been enjoying looking through visual, wordless proofs of late. The low-hanging fruit is mostly classical geomety, but a few examples of logical proofs have popped up as well.

This got me wondering if it's possible to communicate the fundamental idea of Bayes' Theorem in an entirely visual format, without written language or symbols needing translation. I'd welcome thoughts from anyone else on this.
