Ah! I was being stupid then - all the Binary Stars and Neutron Stars have 
this property - I'd forgotten that completely. Actually the version 1 Binary 
Star/Neutron Star variants (which you give) look the most interesting in 
terms of blue line. Neutron Star in particular seems impressively spiky, 
until you notice that in fact the spikes always come in pairs, to form a big 
dodge over four places. The grids are very regular, since basically all the 
bells are doing the same work at the same time, which is what keeps the 
coursers together.
