Waterbear is an oblique spaceship discovered by Brett Berger on December 28, 2014.[1] It is the smallest (in terms of bounding box) known oblique spaceship, superseding parallel HBK. It is also the first discovered "fast" oblique spaceship in Conway's Game of Life.
The helix, fanout devices and syntheses for the helix were found by Ivan Fomichev.
Design
The base reaction consists of a Herschel running on a track of gliders. The Herschel consumes a southwest glider and emits two gliders, one southwest and the other southeast, every 79 generations. Interactions between neighboring tracks[2] are used to create the necessary components to recreate the helix.
In July 2013, Ivan Fomichev proposed a very rough blueprint for the spaceship giving the shape below.[3]
Being made from gliders, the track gradually moves away from the helix, giving rise to the triangular bodies. To prevent the ship from growing exponentially in size, the same procedure used to build the helix is used to "reset" the track. In the Waterbear design, this reset occurs at two points, resulting in three smaller triangles instead of one much larger one. The reset comes at the cost of a fair amount of output-suppressing cleanup, so the design balances the exponential growth and the constant cleanup cost to achieve a reasonably small final area.
