Creative Contextual Drains Edit
Matrix by Honfay Lui

To think of drainage systems as anything but cesspools of waste is really difficult for me and I suspect for lots of other people as well. Honfay Lui is trying to change that way of thinking, and to that effect he designed Matrix, the world’s first contextual drainage system. Matrix is made up of perforated slabs of square metals corresponding to the 26 letters of the Roman alphabet and the numbers 0 through 9. The purpose behind this scrabble-like style of drain is to enable drainage systems to deliver contextual messages much in the same way billboards do.

Pretty clever.
