How can our DHTML animations be smoother?

This is the question Morten Wang addressed so well in his article Smooth animation using DHTML: Can It Be Done?

Now, Mark Szlazak contributes to the on-going discussion with the results of extensive tests that he's performed, and a few improvement suggestions that I'm sure you'll find interesting.

Mark is a chiropractor with a full-time practice in Mountain View, CA. In between seeing patients and authoring papers, Mark has somehow found the time to help cure our DHTML pains, too.

Prerequisites

• Knowledge of the concepts discussed in Smooth animation using DHTML: Can It Be Done.

• Familiarity with the setTimeout() and setInterval() methods. Countless examples of both can be found here at DHTML Lab. A good use of both is discussed in our Fader and Puzzle scripts.

• Familiarity with the new Date() object constructor. See Doc Javascript's Mastering JavaScript Dates

So over to you, Mark.
