yea it sure looks like, but its not a new idea I think its the fact thats its done by a massive company like sun the reason that this is so hyped.

I read an article just over a year ago not about another project regarding 3d desktops called desk3d. The link to the project is here http://desk3d.sourceforge.net/ I would of replied sooner but i was unable to find the source, but i cleaned my room up yesterday and found the article.

the idea is certainly very futuristic but is it needed? a simple start button confuses enough people as it is...
