The orb at the head of the motion controller simply lifts right off the assembly.

Unsurprisingly, the orb is made of a pliable rubber/vinyl. It would have been pretty sweet if it was glass, though.

Three LEDs are responsible for the glowing of the orb, and they are capable of putting out a full spectrum of colors.

They light up different colors to differentiate between different players, and can change colors mid-game, creating another source of user feedback. The color of the orb also changes in response to its environment, ensuring optimal visibility and detection by the PlayStation Eye.
