Lumia 800 and its icons made in pure CSS3. No images, no base64, no SVG, no canvas, just a lot of CSS3 and a little bit of Javascript (with jQuery, of course).
Viewed best with the latest versions of Safari and Chrome in Mac OS X.
I'm not saying that whole Lumia with inretaction done with pure CSS3.
Rendering (!) of Lumia and it's icons made in pure CSS (as I write in the title), interactions and few other things - with the help of JS.
It's still somewhat misleading. Like things like css3 transitions and page states maybe using :target or hash to keep state for "is phone on" and stuff, vs just using jQuery.
