Carnival shuttle is a period 12 oscillator that was found by Robert Wainwright in September 1984 (using middleweight emulators at the end, instead of the monograms shown here). It was used to create the first known non-trivial period 24 oscillator, 186P24.

The carnival shuttle, as shown, comprises two distinct components:

  • The shuttle itself, a reaction between two t-tetrominos. Its stability requires the suppression of one birth per period at both ends of the shuttle.
  • A periodically hassled beehive, which can provide stabilization for two adjacent shuttles.

Using just these two components, a spatial period 15 wick can be constructed. A finite version requires the addition of sparker oscillators as caps.
