an idea I had for a project that never panned out: start with some (digital) sheet music; crop out the individual staves and concatenate them end-to-end in order, giving a long continuous strip of music; then apply a conformal equivalence that maps the *infinite* horizontal strip {0 < Im z < 1} to the unit disc. You'd get a circular image (less a bit, corresponding to the fact that the starting strip wasn't infinite) with, say, the entire violin I part for Mahler 6 compressed into it

oh, this is neat. Radon's theorem: a set of d + 2 points in ℝᵈ can be partitioned into two disjoint subsets whose convex hulls intersect. used to prove a couple other intriguing results about convexity in Euclidean spaces https://en.wikipedia.org/wiki/Radon%27s_theorem
