Snake dance is a period-3 oscillator that was found by Robert Wainwright in May 1972.[1] It has the same tub-like rotor as the snake pit 2 shown below.

Glider synthesis

A 16-glider synthesis for snake dance was found by Jeremy Tan on March 29, 2019 based on a symmetric soup submitted to Catagolue.[2] Long before that, a 6-glider synthesis for snake pit 2 has been known and is listed on Mark Niemiec's page.
