I've seen this effect done before in Flash but it was never anything this well done. This is realy the best WPF demo I've seen in a long time.

The first time I saw something like this is at http://www.birdseyeingit.com but the site is down unfortunately but this is very similar http://www.iparigrafika.hu/pageflip/

That's incredible. Beginning with eBooks and then online magazines the possibilities are endless. I just wonder what some websites could do with FlipPage and similar apps.
