"A toy made from combining Daniel Shiffman's "Boxes" demo from his pbox2d library and the "Input FFT" demo from Krister Olsson's ESS library.
You can use your voice to control the spectrum bars, which interact with the box. You can add more boxes to the scene by clicking the mouse."
 
Utilise les libraries:
 - pbox2d de Daniel Shiffman
 - ESS de Krister Olsson
 
Tentative d'exécuter le code sur MacOS -> Pb avec la library pbox2d:
 The function scaleScreenToWorld(float) does not exist.
