I got similar feedback from Tom Ptacek so... duly noted. I was trying to make a visual allusion to hours being points on a circle, without really describing that in prose (or arithmetic). Hence the big red points on the circle. And really I was trying to use that all as a lead in to the Dali analogy. One thing that I think might help that is completely abandoning the clock face metaphor and just using a simple circle with the hours. I might have the space to attempt to describe the hours as points on a unit circle and show those on each of the respective "clocks". Here's a new version that does away with the clock face metaphor and replaces it with a simple circle, and hopefully addresses your other nits: https://i.imgur.com/0v4kWYy.png -- Tony Arcieri
