For my web comic, I use an animated filter to make things change color if they have roll over events. If more than one is active they change color in unisom. You could probably modify this for your blinking and simply add or remove the filter from things that need to blink.

For example, a symbol may represent a smoke detector and this symbol would blink when in alarm and not acknowledged. Since several symbols may require a blinking effect at the same time, the blinking should be synchrounous so as to avoid driving the user crazy. What are some good ways to achieve this? I was thinking of two methods. One method would be to implement this entirely in java script by creating a "blink list". Symbols would be added and subtracted from the list as necessary. Anytime the list is not empty a javascript timer loop would run at 0.5 second interval alternately hiding and unhiding the population of symbols. The other method would be to dynamically create and delete animations for each symbol that needs to blink. This second method seems powerful (as it would let me implement more complex blinking such as fade-in fade-out) but I am not sure how to synchronize. How have the masses tackled this problem? What are the performance implecations for each approach considering it is possible to have hundreds of symbols blinking on a single display?
