Eureka (or pre-pulsar shuttle 30) is a period 30 pre-pulsar shuttle oscillator in which two 15-generation pre-pulsar shuttle mechanisms each composed of two tubs hassle a pre-pulsar. It was found by David Buckingham in August 1980. A slightly different period 30 shuttle can be created by shifting the top half of the shuttle two cells to the left or right (see below).
