Chilean artist Gonzalo Bascunan was busy setting up an art installation named Flawless yesterday at the Esplanade Park, ahead of the i Light Marina Bay 2018 festival.

The 9m by 5m light installation is one of 22 works from 14 countries, including Singapore, that will be featured at the event, which is running for the sixth year.

Touted as Asia's leading sustainable light art festival, it promotes the idea of becoming more environmentally friendly through innovative and vibrant art displays.

Flawless, for example, is made of hundreds of "leaves" that use solar energy to shine in the dark. The leaves are made of transparent resin and colourful phosphorescent pigments that absorb light during the day, allowing them to glow bright green as the sun sets.

The festival opens on Friday and will run till April 1. It is open to the public, and admission is free.
