Pneumatofony are instruments/interactive sound objects whose construction refers to a few centuries old technique of organ bellows building. On the other hand, their form changes smoothly from regular tetrahedron to cube, while the air is being pumped by the means of foot pedals.
Each of the three Pneumatophones has a set of nine sound generating reeds, different for each instrument (small wooden organ piper, accordion reeds and single reeds), while rotary buttons mounted in the walls, open and close small holes, activating and stopping individual notes (like in the Shruti Box).
