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).[1] It was used to create the first known non-trivial period 24 oscillator, 186P24.

The shuttle itself is a reaction between two t-tetrominos. Its stability requires the suppression of one birth per period at both ends of the shuttle.

There are many ways to stabilise adjacent shuttles:

  • Monograms can be shared.
  • Shuttles can be placed head to head.
  • A beehive can be placed in between.

Shuttles can also hassle a beehive-traffic light-loaf component. The shuttle can be stabilised by monograms, middleweight emulators and T-nosed p4s. The Blocked p4-3 gives the same spark, and thus can be used as a stabilizer too.

Without sparkers on the ends, a spatial period 12 wick can be constructed. A finite version requires the addition of sparker oscillators as caps.
