Audio reactive 3-dimensional goat that transforms depneding on from sound input.
A demonstration can be found here: youtube
In the beginning there is only one sphere (or if you push key '1'), when key '2' is pushed, all spheres from the vertexes of the goat appear, when key '3' is pushed, the triangulation can be seen along with the spheres, when key '4' is pushed, the spheres disapear and the goat is reacting on the sound.
