Programmatic adventures in the hyperbolic plane
Recursion is dangerous. So dangerous that in my professional life I’m explicitly banned from using it in code. After all who would want their aeroplane to stall, their car to crash or their fridge to defrost because of a stack overflow. But it is also, most (but not all) programmers would agree, beautiful and more…

And the projective representation of the hyperbolic plane
For completeness, here is the projective representation of the hyperbolic plane.

Representing equal distances in the conformal representation of the hyperbolic plane
(This is mainly about posting a pretty picture.) As I have previously remarked, the last couple of times I have tried to read Roger Penrose’s The Road to Reality I have stumbled over the discussion of nonEuclidean geometry in Chapter 2 (of a 34 chapter book). Now I feel more confident about the maths but…
