      Perturbations of its reaction also reproduce it in different generations. This might be tamed someday to form glider guns or puffers, as the B-heptomino in Life has been.

      Actually, the period 30 "queen bee" shuttle seems irreparable, as it contains several instances of the Ship neighborhood duriod its cycle. It's the period 46 b-heptomino shuttle that can be stabilized with clocks.
