Jason Summers has found a simple new way to stabilize one of the first known puffer trains, the
Period 20 B-Heptomino Puffer Train, turning it into a small
2c/4 Period 20 Spaceship.
Nicolay Beluchenko has found a way to stablize the edges and corners of the Period 4 Snowflake
Agar, allowing the creation of Period 4 Oscillators.
Other components exist, which can be used to create these simplest forms of the agar oscillator.
Nicolay Beluchenko found a way to terminate some c/4 Waves
found earlier by Hartmut Holzwart, allowing for the creation of a variety of spaceships.
