Traffic Flow
Obey the rules of the road!
In Traffic Flow geometry a line must obey certain limitations on where it can travel. For example a popular subsection of this category is Taxicab Geometry, where lines can only travel on a grid only on the rows and columns that have integers.
Well known shapes can transform into something interesting when forced to obey these rules.
Rules:
1. Lines must travel along the defined grid.
2. Lines may only make 90o turns.
3. There are multiple shortests paths between two points.
