The twin bees shuttle spark is the large and distinctive long-lived spark produced, most commonly, by the twin bees shuttle. After 3 generations it becomes symmetric along the horizontal axis, after 9 generations it becomes symmetric along the vertical axis also, and finally dies after 18 generations.
Since the spark is isolated and long-lived, there are many possible perturbations that it can perform. One of the most useful is demonstrated in metamorphosis where a glider is converted into a LWSS. Another useful one can turn a LWSS by 90 degrees, as shown below.

A period-32 oscillator found by Luke Kiernan on August 10, 2022 produces the same spark. However, trying to convert a glider to an LWSS causes the LWSS to crash into one of the fishhooks.
