Window Phone like a real window
The Window Phone is a concept mobile phone that is able to transform its appearance like a window as per the weather. The phone is designed as a thin, clear and transparent plastic sheet, which remains clear during a sunny day, becomes humid during a rainy day and takes a dump outlook during a snowy day. The user can write text messages or draw pictures on the phone in different weather conditions which will later transform and show as SMS characters. The screen features sensitive interaction with the user and comprises the state of a window in different weather conditions.
