Abstract
A gaming machine includes a rotating object that has at least one configurable surface that may be configured electronically. The rotating object may be synchronized with a video display. Configurable surfaces can use bistable materials, electroluminescent materials, LCDs, LEDs, OLEDs, projection, or other techniques. The appearance of the rotating object is changed without physically changing the rotating object.
Claims18
A gaming machine comprising:
- a stationary video display configured to present a video of a rotating image, the rotating image rotating about an axis of rotation and having a rotational speed;
- and
- a rotating object located in front of the display from a perspective of a player of the gaming machine, the rotating object including a light valve positioned over the rotating image, wherein the light valve is configured to switch between a first mode, in which the light valve obscures the rotating image from the player, and a second mode in which the player can view rotating image through the light valve, wherein the rotating object rotates about the axis of rotation at the rotational speed such that the position of the light valve is synchronized with and remains in front the rotating image.
