All (my) changes are reverted; the Kick-ass thing will have to be dealt by the original mischief-maker.
And as for the browser stuff... most of the differences people were seeing were due to their caches not being refreshed. The background working cursor is pretty much universally supported - all OSes, all browsers (expect perhaps Lynx...
). The favicon (which tends to get cached more vigorously and is more difficult to refresh when desired) was merely an animated GIF, set to a certain color, etc... thus it didn't match many browsers besides Firefox / Windows. Also, evidently some browsers (Chrome) only display the first frame, so it was all the more out of place.
No matter, fun was had by all, even though not all were had by the fun.
