A graphics controller for animating an overlay is described. The graphics controller includes a host interface for communicating with an external processor and a plurality of registers in communication with the host interface.

The logic responds to values stored in the registers to cause display registers containing the coordinates to be updated every x number of frame refreshes, wherein x is a positive integer.
