A day in the life of the Mid-levels Escalator, Hong Kong. The longest public moving walkway in the world, the Mid-Levels Escalator connects the Central business district with residential areas higher up the mountain. Breathing new life into once run-down areas, a whole new nightlife zone has sprung around the 'Electric Steps'. This 5-minute short, set to music by Hong Kong's own 'Celestial', compresses 18 hours of footage from 3 cameras into a multi-dimensional symphony.
