Never knew how to read a graph ? Never understood the axes thing ? Then the “XYZ” project is just the one for you ! Either torture devices or rides for smartphones, these ceramic objects link the movement detected by the smartphone’s sensors to the graph that comes up on the screen. Spin the wheel, stretch the rubber band or keep your ears open, it will all seem much clearer !

See for yourselves

How it works
