Hi Jon, your first comment. I don't have comments on my website so I have come to pollute yours instead : )

I saw this too, actually I reckon the effect could be quite useful on some web pages, not as a navigation aid (it's kind of annoying when buttons jump around as you try to click them) but to enlarge thumbnails of images for example

There's a mirror up at

though that'll probably come down at some point.
