    ,a display controller connected to the storage device and to the display device so as to control the amount of time individual ones of the video cells are displayed on said display device such that the animation sequence is displayed in a pre-determined time period and wherein, if the pre-determined time period is less than the time required to display each cell of the sequence for one update period, then said display controller processes at least one selected cell at a rate faster than the update rate of the display device so that the selected cell is not displayed, such that the total number of update periods for the cells in the animation sequence that are displayed produces a sequence display period that is substantially equal to the predetermined time period.
