Nobody wants to ride merry-go-rounds anymore because horse-drawn carriages are so last century. That's why Manhattan's Battery Park is setting up the first aquatic carousel this summer. Instead of mounting a horsey inside a tacky gold-plated circus tent, visitors get to coast through a nautilus-shaped carousel on the back of a dolphin or a manatee while enjoying 360-degree projections of sea creatures floating around them on windows made of SmartGlass.

The same architecture firm that's making this carousel, Weisz + Yoes, already improved Battery Park with its strange spiral fountain that shoots right up from the sidewalk. Image by Weisz + Yoes
