Assembling the colourful wooden cogwheels on the tableau is only half the fun. Only when the big blue wheel is cranked does it become clear whether the plan has worked – are all the wheels turning? And most importantly, in which direction are they rotating? The illustrations have been carefully chosen so that the running cogwheels create a "complete artwork": Learning should always be this creative and playful.
