Click on the blue buttons to drive the taxicab
(requires Flash Plug-in)

There is only one way to drive the distance of four blocks to the library.

But there is more than one way to drive the shortest route to McDonald's. Can you find them all? How many different five block routes can you take to McDonald's?

The point of this animation is to show you that taxicab geometry does not meet the first axiom -- more than one straight line may exist between any two points.
