Queen bee shuttle/Snippet

The queen bee shuttle can refer to one of two period-30 oscillators (trans- version shown to the right) in which a queen bee travels back and forth between two blocks. Other stabilisations exist, such as ones that involve the eater 1, called the buckaroo. The queen bee shuttle is the basis of many known true period p30 guns, including the infamous Gosper glider gun. It was found by Bill Gosper in 1970 and was the first period 30 oscillator to be found. It is the smallest known oscillator with period greater than 15 and about the 18th most common naturally-occurring oscillator.
