Classical Concert Hall Online

"It was only a matter of time before someone created a sophisticated site like this one featuring live concerts for a global audience with CD-quality sound and high-definition video on a digital platform dedicated to the world's best orchestra. First, you'll need to do a stream test to check the power of your machine and connection. Click How It Works to run the test. Once you have verified you have a machine and a connection that can stream concerts at full-screen, click Archives to watch some free footage. The site is essentially a pay-per-view experience, but there's enough free content to whet your appetite." ~ Adobe.com

Plugin to the Smartgrid

This site is so professionally done it's incredible.  The content is very straightforward, narrated well, includes splendid animated illustrations and really shows the general pathway to clean energy.  A well-done branding tool for GE.  Site was done by Goodby, Silverstein & Partners and North Kingdom.  The augmented reality section is is not necessarily new technology, just one that is now mass-consumable with an installed base of webcams and flash player.
