Green lines make Zometool more versatile and complex.
Green lines hijack the pentagonal (red) holes in the ball. But because of their design (double kinked) each strut can go into a hole in one of five different ways adding 30 new directions from each ball!
The most basic way to picture what the green lines do with a square. The green line is the diagonal line between corners.
Of course this is just the beginning Green lines open up a fascinating new world of building possibilities including truncations ruled surfaces and some important basic shapes as well; for example 2 of the platonic solids (tetrahedron and octahedron) can only be built properly with Green lines.
