The "GENESIS Malette" is a set of simple physical objects: balls, springs, and others, with a few tools and a variety of specific devices, which can be stored in a briefcase (malette, in French), and accompanying GENESIS (the sound synthesis and musical composition software developed by ACROE). The "Malette" is a material representation of the GENESIS virtual world, which is itself a virtual representation of the real material world. All this works accurately and in a way that allows "fine aesthetic fashion understanding".The "Malette" is a support, a "companion" to the pedagogy of GENESIS, as well as a system allowing building a wide variety of objects that can be exposed for themselves.
