This is an awesome work, really. The design style reminds me a lot of Eric Jordan's style (2advanced Studios) [0]. Not really a new style, but nice to see that Interaction Design with open technologies (HTML/JS/CSS) is arriving "there", where (believe or not) Flash was 10 years ago...

I've been waiting for this moment for years. Hopefully this will set a new trend.
