Pi wave

A pi wave is a wave made of pi-heptominoes mutually stabilizing one another. Examples are:

• An infinite line of pi-heptominoes may be arranged to produce a 3c/10 pi wave which travels orthogonally at a speed of 3c/10 with period 30, and leaves no debris.
• 3c/14 pi wave is a pi wave that travels at 3c/14 diagonal.
