Festival-goers could put on a pair of mixed-reality glasses and walk through the virtual blue structure as it changed shape in response to their movements. The installation was intended to encourage visitors to explore the potential of manipulating a perceived environment.
For 16 days, the world-famous arch on the Champs-Élysées was covered by 25,000 square metres of silvery fabric, secured by 3,000 metres of contrasting red rope. People were able to touch the architectural work as well as observe the installation from the Arc de Triomphe's terrace.
Japanese artist Yayoi Kusama covered trees at the New York Botanical Garden in her signature colourful polka dots as part of the park-wide 2021 exhibition Kusama: Cosmic Nature.
Other installations by the artist in the gardens included a lake filled with 1,400 mirrored steel balls and a large pumpkin sculpture made from bronze. Several installations were also playfully placed inside the buildings of the New York Botanical Garden.
Saudi Arabian artist Ajlan Gharem used chicken wire to create Paradise Has Many Gates, a 10-by-6.5-metre cage-like installation that can be used as a Muslim place of worship.

Studio Roosegaarde transformed a 20,000-square-metre plot of land into a light installation designed to highlight the beauty of agriculture.
After a trip to a farm, designer Daan Roosegaarde learned of the potential of photobiological lighting technology in promoting plant growth and resistance to pesticides. Inspired by the technology, he installed red, blue and ultraviolet high-density LEDs into a field to create Grow.
This year's Dubai Expo saw a range of impressive pavilions including The Dutch Biotope, which has translucent solar panels on its roof. The designer, Marjan van Aubel, hoped that the colours and lights would demonstrate that solar panels could be beautiful while also powering the exhibition.
"At different points in the day the light, shadows and colours will change and so I hope it feels like a constantly changing immersive experience, similar to the light falling through a stained-glass window," van Aubel told Dezeen.
A panelled membrane was supported by a web of steel tensile cables, forming a transparent dome with views of the surrounding skies. A series of vents in the floor pumped air into the dome to ensure its bulging appearance was maintained throughout the show.
In a year that saw multiple designers use trees to highlight the impact of climate change, design studio Superflux transferred 415 dead black pine trees from Austria's Neunkirchen region to the country's capital for Invocation for Hope.
Living plants were then arranged around the trees and a reflective pool, creating a tranquil oasis in the middle of the Museum of Applied Arts. The designers wanted the installation to embody "a post-Anthropocene landscape where humans learn to live in harmony with nature".
