I love to see that they're using jQuery for the animations. I'm anxious to see more people going this route over Flash. Not that there is anything wrong with Flash, and it may very well be better suited for this type of work, I just want to see the uses and plugins for jQuery continue to evolve.

I sure hope not. Their simple animation spikes one of my cores just to animate some clouds. Not a very efficient way to animate things.

Newer WebKit browsers use the GPU to accelerate css-transform animations (giving your CPU a break). Check out the example on this page in the latest version of Chrome or Safari, for example:

Thanks for the resource link. I can't wait until Firefox can do this. I want to use webkit animation in my website, but for now they would only work in Safari and Chrome.

When I see what Flash does to my CPU on OS X I somehow doubt that it is more efficient.

Of course, you're not comparing fair examples of SWF vs. jQuery. I guess it's ok to ignore the obvious advantages of Flash if you can bash a full features app or animation compared to the Google Wave error page.

For me, on Mac OS X, flash is much more inefficient than JQuery animation, especially in Safari and Firefox.

What's good about using JavaScript and known libraries is that you can just write a userscript to reduce the framerate. With Flash, it would be all or nothing.

No spikes here...

Wow, first time ever I got down to zero...

That's eager, not anxious ;)

You know, I almost used "eager" too. English was never a strong subject for me. Come to think of it, neither was math or science or history. ;)
