Biolumen, by Radha Chaddah x RAW Design

MEDIA RELEASE – Yonge-Dundas Square is proud to present Biolumen by Toronto-based visual artist and scientist Radha Chaddah and architectural firm RAW Design from March 1 to April 1. Biolumen by Radha Chaddah x RAW Design is an immersive experience with changing light, texture, and sound. The art installation features ten large luminescent structures where art, science, and nature merge. Inspired by deep-sea Radiolaria, “Biolumen” represents resilience and beauty in harsh environments.

Installation Name: Biolumen by Radha Chaddah x RAW Design
Where: Yonge-Dundas Square, 1 Dundas Street East, Toronto, Ontario
When: March 1 to April 1, 2024
Hours: Daily from noon to 10pm
Admission: Free

At night the sculptures become luminescent and glow from within and project colorful beams of light through their perforated skeletons, creating a dazzling display on the surrounding environment.

In the daytime, the differentially coloured inner and outer layers of the Radiolaria sculptures reveal a different way to experience sounds and sights of each of these sculptural creatures. Accompanying sounds are an original score that emit from within the sculptures. It is an ambient sonic landscape that evolves over time and with interaction.

Biolumen, by Radha Chaddah x RAW Design, is a co-production of Quartier des Spectacles Partnership, the City of Mississauga and Culture Shawinigan, with distribution by QDSinternational.

Julian Sleath, General Manager of Yonge-Dundas Square shares, “With the dark and cold days of winter, we are thrilled to present this radiant and immersive art experience created by Torontonians to brighten up the winter season. Toronto residents and visitors will be enchanted and inspired by Biolumen by Radha Chaddah x RAW Design and we can’t wait to see how they interact with the installation.”

“As an artist who lives and works in Toronto, I’m excited to see Biolumen shown in my hometown at Yonge-Dundas Square,” says Radha Chaddah, Biolumen’s creator, visual artist and scientist. Reflecting on her artistic inspiration and intention with her work, Chaddah also shares, Biolumen was inspired by Radiolaria, which are tiny single celled animals. Their name means ‘small sunbeam.’ Ocean floors are thick with their astonishingly beautiful skeletons, made from silica. Radiolaria live symbiotically with algae who feed them with sugars they make from sunlight. Some Radiolaria are bioluminescent because of the bacteria that live within them. The visual and sonic harmonies created by this installation are a tribute to symbiosis, and the ideal of humans living in balance with nature.”

Suleman Khan, Intern Architect, from RAW Design adds, Biolumen provides a captivating peek into the interplay between Radiolaria and our environment. Through immersive design, we aim to evoke a sense of emotion, fostering a personal connection to the natural world. As designers, our goal is to create active public spaces that not only stimulate the senses but also inspire contemplation and appreciation for the delicate balance of nature."
