QT Sydney, Australia’s hottest new design hotel boasts style, sex, and quirk. To add to that quirk, we proposed an idea to QT to take the simple human experience of riding an elevator and bring it to the next level (metaphorically). Alchemy developed a program that detects the number of people riding QT Sydney’s elevators and plays music accordingly. As people come in and leave the elevator, the music changes. Less people = slow music. More people = party music.
