Glasses is a period-2 oscillator with a number of ways of stabilizing the edges. It features two covers and two snakes acting as induction coils.

A 17-glider synthesis is known for a stator variant of this oscillator (shown below) which is rotationally symmetric and uses two houses instead of snakes for stabilization.
