Mobius Strips, Holograms, flying and space travel/colonization are why I got a degree in Physics.
So naturally I think this bridge, proposed for a new waterside park in Jersey City, NJ, is so exciting.  I love the idea of the infinity bridge.  A very clever design by nARCHITECTS. The bridge is meant to visually represent the connectivity and continuity of the park with its surroundings and history while also serving the practical purpose of easing circulation within it.
