Forget about TomTom – the TamTam Flash GPS navigation device is a concept that we would probably love to have immediately – assuming current battery technology is capable of keeping up with it. This projector-style GPS navigation system will project navigation information on your path so that you can see up close and personal one bright red arrow to know whether to stay the course or make a turn. Apart from that, it can also project the map on a surface for you to orient yourself.
