Sometimes when you arrive to a foreign country there are some difficulties to find bureau providing the information on the city or how to get to any destination.
I have an idea to install a projector or video screen in the central part of every country of the world to keep all the travelers and visitors well informed about all they need.
This projector will show the country info, culture, people, history, places you are intended to visit and areas of instability. Just take a tight-filled purse and you will feel comfortable traveling any place on the Earth.
