The Flash Anthology: Cool Effects & Practical ActionScript – Chapter 3: Animation Effects
The fads of Internet design may come and go, but one thing that will never change is that the more dynamic you make your Flash creations, the more engaging they are to the user. This dynamism can be counterproductive under certain circumstances, especially when multiple effects battle for the user’s attention, or the effects are too garish. Identifying the key to effective animation is like the search for the Holy Grail. What some users think is a cool effect, others find patently uninteresting—and vice versa. Never lose sight of the importance of striking a balance between the interface and the animations you’re attempting to produce.
