Invented by Jack Levy of the City University of London, the 'Levytator' is the world's first sinuous escalator, designed based on a surprisingly simple concept.

Using a continuous loop of steps, the 'Levytator' consists of both an up and a down staircase, making the entire system more efficient than preexisting designs. Each tread is formed as a curve, enabling the easy turning of corners that give the 'Levytator' its meandering mastery, whether ascending, descending or traveling level.
