A pair of Gliders can be used to shift a Pentadecathlon over one cell while changing its phase
by four generations. This interaction takes a total of 34 generations to complete.
From this, David Bell has built a structure, that he calls a "Pentadecathlon Crane", which
uses this interaction to continously "lift" the Pentadecathlon. It uses a set of four
Period 184 Slide Guns (Glider Guns in which every Glider produced follows a different track, each
farther from the main gun mechanism) to strike the Pentadecathlon every 94 generations. (Shown here
are Generations 0 and 376, with the Pentadecathlon having been shifted four cells to the North.)
Nicolay Beluchenko also pointed out that this mechanism can be used to create Pentadecathlon
Hassler-type oscillators. Hasslers are oscillators in which a simpler object is repeatedly shifted
back and forth. Here's a Period 188 version.
