samlittlewood: http://280slides.com/ - CappucinoNot sure I would necessarily use Cappucino myself, but to me, it demonstrated that treating javascript+DOM as a target for a higher level interface can work, and can work well.I guess Outlook Web Access should get an honourable mention - I guess that was the first widely available app. that demonstrated that is was at least possible and was useful.
