A center disc can rotate the center five pieces
(i.e., the center piece and the first piece on each arm), a middle ring can rotate the next two pieces of each arm,
and an outer ring can rotate the outside pieces of each arm.
In addition, a plunger can be temporarily pushed in to offset all of the pieces of a row by one unit
