摘要
The equipment is formed by a set of elements of transparent rigid material, that can be placed side by side and forming together multiples and sub-multiples. The set of elements comprises plane surfaces and volumes, elements more or less coloured and also mat opaque elements. At least one of the elements having the shape of a plane surface is grooved and the thickness of the grooves corresponds to the thickness of the plane elements of the set.
