Well, Apple's current homepage with the Panther countdown ... when loaded, top tells me Safari is using between 35-45% CPU, when not loaded, Safari uses less than 5%. Odd.
same here on OSX.com i am at .8% and on Apple.com i am 42%, however this really isnt a huge deal since i am not usually on the apple index page that much
It's a simple javascript, the clock is a bunch of .gif's.
EDIT: Too much code to post. Just go there and view source. A lot of "document.write" tags in the body too. Maybe because of recent IE compatibility changes?
Zammy-Sam, that site not only sucks, but uses about 80% of my clock time...
Porteous, for me, at least, the Panther count-down is still on the Apple Homepage in one of the small boxes near the bottom of the page. It is a Quicktime applet now though.
