Arrow’s Theorem: Visualizing 3-Candidate, 3-Voter Elections with Hexagons - Andy’s excellent explorable explanation of Arrow’s Theorem, accompanied by a YouTube video, and a software repository. I really like this because it’s the only constructive proof I have seen that starts with Unanimity, IIA, and determinability (no ties) and ends with dictatorship.
Political Sim - by Accurate Democracy - the earliest interactive voting simulator - It requires some technical know-how to get going.
Median Voter - a simple conceptual experiment with discussion of strategy and median and mean
RBVote Calculator - I copied all of his methods into this simulator under “RBVote”.
