Mikael Bergkvist developed “ZAP” to get uniformity for JavaScript effects in browsers. In general many effects run around in a modern browser, and lag on old ones. We have talked about the need to have a Timer thread that you can tie into to get the work smoother.

ZAP is a widgetplus project which boosts javascripts up to eight times the speed without having to resort to a plugin of any sort, by using a completely new approach that takes into account how the javascript engine is actually written. It’s also making sure – automatically – that the set speed remains exactly the same regardless of what browser you use.

Once set to a certain speed, it stays that way – regardless of the browser being used.
