...but WDW had the concept first when it remodelled the Communicore
centers at Epcot into Innoventions East and West.
The rotating building that is now home to Innoventions was originally
built for the Carousel of
Progress (which is now at Walt Disney World). After CoP moved
out, America Sings moved in. Eventually animatronics from AS made
their way into Splash Mountain
(and a few into Star Tours). The
rotating theater sat empty for years until the 1998 redo of Tomorrowland.
Today both levels of the building are open and full of tradeshow
type exhibits of gadgets, video games, and other electronics. Most
of the items on display are things you could buy at any high end
electronics shop but there are a few interactive exhibits that are
worth a look.
