Finalist Voilà! Awards (2014)

 

Have you ever needed a compass just when you don’t have it by hand? Maybe you don't have it with you as it is fragile or too big? Circa rule has been designed to solve this problem.

 

It is a small rule, with a size smaller than 17 centimetres, which not only has the usual rose of measuring, but only allows drawing circumferences. This is possible thanks to a series of small holes placed all along the rule and a larger one at the end into which the finger is put in order to set the centre of rotation.
