Double X is a period 46 oscillator based on the twin bees shuttle that was found by Robert Wainwright and exhibits two interesting reactions. First, it shows how a twin bees shuttle can be used to convert a glider into a lightweight spaceship. Second, it shows how a head-on collision between two lightweight spaceships can produce two gliders.
