[Interlocked] Trace

Trace is done from a 1/4-tag-like or diamond-like setup. It is sort of like Jay, but with people working in inconsistent groups and doing different calls. Each end of the center line, and his adjacent person, do the first call with the outside people that he faces. That call is done in a distorted 2x2 box. Those outsides work with the other two people in the center line for the second call, which is also done in a distorted 2x2 box.

The only significant facing directions are those of the ends of the center line. Everyone else's actions are dictated by their locations.

On Interlocked Trace, the end of the center line and person once removed from him work with the outsides that the end of the line faces. Those people work with the other two once removed people in the center.

Reasonable shape-changers are allowed, as for the Jay concept.

There is an obsolete usage, in which numbers are given instead of calls. Do the indicated number of Box Circulates.
