CAUTION! GREENLINES ARE FOR EXPERIENCED ZOME USERS ONLY! DO NOT BUY THIS ADVANCED KIT UNLESS YOU ALREADY USE ZOME! THIS IS NOT A STAND ALONE KIT. NOT RECOMMENDED FOR CHILDREN UNDER 12.
GreenLines expand the Zome System from 31 to 61 lines in space. How?
Blue, Yellow and Red lines form 31 lines in space. They are based on the Cube, Dodecahedron and Icosahedron -- 3 of the 5 Platonic Solids. GreenLines build the other 2 -- the Tetrahedron and Octahedron. GreenLines provide the 6 diagonals of a cube -- the 6 edges of a Tetrahedron. And 5 different cubes are associated with a Dodecahedron, so GreenLines provide 6 x 5 = 30 new lines in Zome System -- for a total of 61 lines in space!

Whole green lines are diagonals of a square. If the edges of the square are one unit in length, a whole green line has a length of the square root of 2 and is at a 45° angle to the edges of the square.

|
Half green lines are half as long as whole green lines. If the edges of the square are one unit in length, a half green line has a length of the square root of 2/2. (Half blue lines are also available.)

Blue-green lines have the direction in space of a green line, but the length of a blue line. They can be used (often with blue lines) to make special-case models such as a regular octagon or the regular and semi-regular polyhedra of equal-edge lengths. Blue greens are not truly part of Zome geometry and should only be used in special cases like those mentioned above!
USING GREEN LINES
Combined with other Zome Kits, Zome GreenLines expand the Zome System offering new angles, new structures and a world of new possibilities. Zome GreenLines are fully compatible with all current Zome components.
Now you can build:
- True diagonals to Blue Squares and Cubes
- Oct-tet Trusses
- Regular Platonic Solids and their Truncations
- Regular Octagons and Archimedean Solids (in BlueGreenLines)
- And much more...
GETTING STARTED
Take a look at the ends of the Green Struts. Green Struts have a diamond cross section, yet go into pentagonal holes, the same holes that the Zome Red Struts usually go into. This makes it possible to build Zome in an entirely new direction! There are 60 green vectors but only 12 pentagonal holes, so a green strut can take 5 positions in any pentagonal hole!
With a little practice you will recognize the symmetry of green lines in relationship to blue, yellow and red lines, and building will become easier.
Start with whole green lines by building a regular tetrahedron and a regular octahedron with familiar Zome frameworks. These models can also be built with 2 half greens per edge, but you cannot use blue-green struts, since they are improper lengths to work with other Zome struts.
