This is just a demo, each <div> is one cube. Its x, y and z
positions are defined by its attributes. Its color is defined
by its class.
Y is the vertical axis. The higher the value the lower the
cube appears on the page.
X is the axis with a slight positive slope. The higher the
value, the farther right and up on the page the cube appears.
Z is the axis with a slight negative slope. The higher the
value, the farther right and down the cube appears.
