There is nothing stronger than taking one element and repeating it until you make the viewer forget its initial purpose.

This is what I did in the small bathrooms of Darb 17/18; Cairo's most happening cultural center.

Took that ruler, and had it take me to it's angular waves.

 

The bathroom ended up looking very colorful and fresh... but it's out of order most of the time, which is a great pity for this artwork.
