anti-fogging glassPilkington, PPG, Asahi Glass Co. and Saint Gobain (glass companies all) have designed a titanium dioxide coating for glass which, when exposed to UV light, breaks down oil on the surface, allowing it to be easily washed away and causes water to "sheet" over the surface (which prevents it from fogging). It can also be used as a coating with the same properties, something which could prove useful for Tablet PCs (if they ever really catch on, of course), PDAs, or anywhere else fingerprints are unwelcome.
