Petalclouds

Spanning across the Central Galleria of the Terminal 4 of Changi Airport in Singapore, Petalclouds creates a performative bridge across the land and transit side of the building. Its 45 minute long looping performance welcomes and greets the passengers through their travel.

The artwork evokes the impression of clouds moving slowly in the sky. The collective choreography of the six sculptures based on classical sonata form results in a synaesthetic interplay of form, light and music that can be seen from all around the terminal.

The six clouds spread across the 200 meter long void consist of 16 elements each, inspired by flower petals. The 192 motors are choreographed to move the elements on vertical planes and synchronized with musical composition by Olafur Arnalds. The music can be heard in 6 listening areas as well as through a mobile stream.

The seemingly light and minimal physical presence hides a number of considerable technical feats in safety engineering and operations.
