Traffic circle (or p100 traffic jam) is a period-100 oscillator found by Noam Elkies on October 15, 1994.[1] It works by using four fumaroles and four molds to hassle a traffic jam so that it moves around in a circle.
GUYTU6J and iNoMed found an 81-glider synthesis for this oscillator on June 1, 2021.[2] Matti Ward reduced this to 77 gliders on November 10, 2021.[3] On March 18, 2024, KtT reduced the cost to 75 gliders.[4][5]
