Ever since the beginning of mankind, communication has been a primary need along with eating, drinking and sheltering. Consider the first wall paintings of the early humans. Or imagine the symbols drawn on glorious palaces and monumental temples in the ancient ages. It was always important for mankind to express themselves through symbols, or to register certain things. The long journey starting with the wall paintings and continuing with hieroglyphs, cuneiforms, and the alphabet as we know it, has reached today to emojis, returning all the way back in the age of technology. Once again, we communicate through simplified symbols to express our thoughts and feelings, with tablets in our hands.
