Window Phone - concept phone On one hand, clear conceptual phones already, so this is not just the first, but on the other, the so-called Window Phone has one impressive feature - its transparent housing varies depending on the weather! Thus, in the sunny days, the screen will be completely transparent, on a rainy day it will appear «virtual» drop, but it is covered with frost frost. Ie translucent screen will look like as well as present a window into a variety of weather. I do not know how it will be practical, but at least, very original! :)
