Continuous Closure from the Bathroom Sign

I used Gestalt's principles of:

-Closure (when we fill in the blanks of an object even though some 

of the information is missing)

-Continuation (when our eyes move from one element to another)

When looking at my image you can tell that it's a bathroom sign even though some of the image is missing.

The black and white portions of the image help direct your eyes to the red bar.
