Perpendicular lines or parallel lines are two examples

The Rainbow/Push Coalition
(1,2,4,8,16,32) With lines connecting 1 and 32, 2 and 16, and 4 and 8.

There are a number of things that could be formed by adding a line between 2 lines. This could form an H.
If Chuck Norris has too many skittles he can, then he barfs and a rainbow is formed.
