How about a smart mirror.
Recently I was speaking to a friend and we talked of how in the future we might have amazing mirrors. One where you swish in mid-air and details about the weather and your calendar come flying by. A mirror that tells you how to best put on your tie(or teaches you how to do so). All that sitting on a simple(ish) bathroom mirror.
It is such ideas that disturb me at night. They make my mind spin and give me sleepless night (well some other times its my neighbors Subaru). Such conversations start with ‘in the future’ but *&^% we are in the future.
Perhaps someone will build that smart mirror one day or a solar powered billboard (look at all that back a billboard exposes cant you just charge it) or perhaps trees that produce wifi. In the meantime…….
