"The Wonder Rotunda launched this month. You might call it a 'virtual world's fair!' This site is a virtual educational theme park designed to get kids thinking about the planet, what they're interested in and passionate about.
On Wonder Rotunda, kids can do everything from zipline through a tropical rainforest, steer a submarine through the human digestive system, dive the Great Barrier Reef or operate a smoothie stand! Jam packed with 13 'game shows,' there is never a dull moment - yet they are learning and exploring every step of the way.
And it features NO ads or social chat rooms. All fun and educational. Created by a D.C. dad who was inspired by the 1964-65 N.Y. World's Fair and wanted to recreate that experience in a new, fun online experience. A one year pass to Wonder Rotunda is $45!"
I think we'll continue to see more of this sort of site - at least I hope so. I do like the video on the homepage.
