In today's newspaper:

A professor at the University of Alberta is working on developing a glass surface that cleans itself.  "If we can reduce microtextures to nanotextures, we could have glass that cleans itself."

One step further, would a glass that repairs itself be good or bad for the restoration business?

Reminds me of Mork and Mindy:   Nanoo,  Nanoo !
