@RunneR : It's not targeted to just children. He's trying to say that WWT is an awesome tool for ANYONE. Including children who might like to explore. As for adults, there lots of info., links to well-known databases for more info., and a lot of other imaging tools scientists would find pretty helpful.
I just wished they didn't show all this good stuff, until they would release WWT soon. The anticipation is driving some people nuts!
