A Message To Extra Terrestrials

Did you know that in 1972 and 1973, NASA launched two, unmanned, robotic space probes called the Pioneer 10 and the Pioneer 11, respectively, into outer space? And on these space crafts there were gold-anodized aluminum plaques depicting a friendly message addressed directly to extra terrestrials in an attempt to communicate with them just in case the Pioneer 10 and 11 came across any of them? It's kind of a weird concept but kind of fucking rad too, especially from a graphic design point of view. How do you speak to someone or something in symbols? How do you find ways to express your thoughts without words and sounds? How do you get someone or something to understand you when neither party have anything in common? Here it is if you've never seen it.
