π Day materials
I co-organized π Day 2015 at Illinois [Link]. Below are some of the materials I produced for that event.
Advanced π posters
Euclidean π - constructs and measures inscribed and circumscribed polygons
Hyperbolic π - does the same but in hyperbolic space
Galperin's billiards - sketches a proof that Galperin's experiment results in the digits of π
