The queen bee shuttle is a period 30 oscillator in which a queen bee travels back and forth between two stabilizing ends. The shuttles were originally stabilized against one another in a square of eight shuttles, though there are now a number of known ways to stabilize the ends. Some simple methods of stabilization involve blocks; for a method involving an eater 1 see buckaroo. The queen bee shuttle is the basis of all known true period 30 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.
