Why a frog?
Do you know the "leap frog"? It is this phenomenon which sees emerging countries catch up in terms of infrastructure and technologies by skipping a generation of products to provide directly the most modern. For example, China suddenly switched its antique locomotives for the TGV, without purchasing or producing more conventional trains. Or Africa which is massively equipped with cell phones without having known the stage of fixed phones due to the absence of copper wire networks. Or those large cities in full development, concerned about the consequences of the rise of the automobile on their territory in terms of serious congestion and large CO2 emissions, and which are questioning how to avoid or limit this "car" stage by not building, for example, parking around airports to encourage their access by ultrafast public transport into the heart of the nearby city.
Away from small steps, frogs allow for large jumps to leap over the delay and obstacles in order to be at the leading edge and stay a step ahead. This is why Distinct Communication symbol is a frog.
