Play the HPSTR Pyramid instrument

The HPSTR Pyramid has no visible interface but is the interface itself. The tetrahedron is played by pressing or tapping its sides and by altering the spatial orientation.

The HPSTR pyramid was developed by Flavio Gortana within the scope of the "Musical Interfaces" class 2012/13 at FH Potsdam.
