Since the dawn of Man, signs have already played a crucial role in his life. Primitive man broke leaves, etched on tree trunks, read footprints, or drew on cave walls or on stones.
Those signs were all meant to convey a message – usually to convey information or warning of potential serious consequences if ignored.
We don’t break leaves or etch on tree trunks anymore, but our lives are still governed by signs. In fact, more signs – from those on laptop or smartphone keyboards to street signs along the roads you drive through each day.
Then as now, they convey the same message, but more complex, comprehensive and baffling, at times.
