Self Cleaning windows to be modelled after butterfly wings

Why did they not come up with this before I put up those huge kitchen windows!!?! And whatever happened to the self-cleaning windows that were supposed to use the sunlight to somehow clean itself? I saw an advertisement for these windows in an Italian magazine once. I've heard no more about those.

Scientists are studying butterfly wings in order to develop new self-cleaning windows and windscreens. The French researchers have developed a technique for replicating the microscopic surface of the insects' wings, which repel water and dirt. Minute waffle-like structures on the wing make it difficult for water droplets to spread out, and as a result they roll off, taking dirt with them.
