Nice.  Are there any minor examples?  There are false ones such as
suggesting that there is no fundamental obstruction.

Regarding practicality, we tried a course of my example last night, and it 
was reasonably fun.  There are 180 mutually true courses (half of the 
in-course ones with 78 fixed), giving 5760 (I haven't tried to join them 
together, but it should be possible).  I suspect there are better 
unprinciples out there though...

Changing the offset of the 2 lines within this structure I don't think will be possible.
