ConwaysHat

A jolie "frenchy or not" flashmob choregraphy simulator!

All participants will be arranged as a grid (8 neighbours around). Each participant carries a set of colored hats ordered in a list (same for everyone), and wears only one. Before the event starts, they choose randomly a hat to wear.

A rooster is used to orchestrate the choregraphy. Uppon a the rooster screams, participants will look around them and simultaneously (not one at a time) apply the following rule:

Each participant counts the number of neighbours who wears their next colored hat in the list. If this number is greater than the threshold, then he/she will wear its next colored hat. Else the participant doesn't switch hat.
