International langauge
If you go into an airport, you see signs written in two langauges.
The first is the local langauge, the other is a langauge of symbols representing what is being said in the local langauge.
Many attempts have been made to design an international langauge, but what if someone could design a written langauge based on symbols so anyone can understand.
Why not make airport symbols writeable to express ideas outside spoken langauge with ease?
