Puzzle 60 solution: 43 parts


This one is pretty similar to jcross’s, only mine uses more parts and especially more crossovers. So given that jcross’s does essentially the same thing as mine, but jcross’s is better, why am I posting mine? Dunno, just thought it was worth adding another variation.


…I quite like Paul’s bit at the bottom center to alternate sides; integrating that approach into mine would bring the part count of mine down to about 41. But that’s still not as good as jcross‘s 37.
