ABSTRACT:
A system and method for creating and displaying dynamic special effects on graphic text objects. Preferably, the special effects are displayed in stages or animation frames, such that the special effects appear to move. In addition, the special effects preferably are displayed for a predetermined period and then the original text objects are redisplayed without the special effects. The system and method include alternate embodiments for displaying at least three different dynamic special effects: fade-out, shimmer, and sparkle. The fade-out embodiment erases progressively larger portions of a selected text object with each animation frame. The shimmer embodiment shifts consecutive rows or column of pixels of the selected text object in opposite directions with each animation frame. The sparkle embodiment displays random pixel patterns, referred to as sparkle grids, over random locations of the selected text object.
