Yep, and they're still useful: I use a logarithmic computation for fading elements in and out with JavaScript, and by pre-computing the values for each step and storing them in an array, the fade still looks smooth even on older hardware.

I'd love to see this in action - do you have a link? Do you literally serve a precomputed array as part of the JS and iterate over that using opacity/IE filter/whatever, or is it more nuanced than that?

Sure: http://shomi.associatedtechs.com/
It's not precomputed server-side, it's precomputed when the fade effect is called in the JS. The value for each step is then stored in the task object that performs the fade. Which is cheating a little bit, I suppose, but this way, I can fade from any value to any value, at what appears to be the same "speed", without any glitching.
