So that's how he does it....

Another Tim Hamilton oddity today, with the topic of "Surrealist mathematical formula Skirball". Two stones with one bird today, as I never drew a picture for yesterday's Drawbridge topic "the Path", despite being the one who suggested it (well, my girlfriend did, but it's all the same...). There is no higher sin on Drawbridge than suggesting a topic and then not contributing a drawing-- thems folks are lower than a horse thief in those parts.
