Interactive Cube is a sample Cube that can be controlled with mouse to rotate around its axis and each face does different set of things, when clicked, based on the colour slider at the left.

 

So for example, on 1 face, a particle effect starts that changes between Fiery, watery and Icy effects from Red to Blue. 1 Face changes its shape between the slider, another changes the cube into the Cube Map of Earth and the Slider controls the placement of the Sun around it, etc. etc.
