English - In 2011, it is time to look back...a long time back! To celebrate the tenth anniversary of the original Funkenschlag, designer Friedemann Friese will take you back in time and let you relive the early beginnings of mankind. True to the name of the German edition (a literal translation of which is "Flying Sparks"), it is time for Funkenschlag: Die ersten Funken, or "The First Sparks".
