French Artist Cyril Lancelin Creates Vibrant Inflatable Rainbow Labyrinth in Grand Rapids

Sayart / Sep 20, 2025

French artist-architect Cyril Lancelin has unveiled his latest monumental installation, "Pyramid Curbs," at the Return to the River festival in Grand Rapids. The large-scale inflatable artwork transforms the urban landscape into an immersive playground of color and geometry, inviting visitors to step inside a three-dimensional rainbow maze that redefines public space.

The striking installation features intertwined tubular forms that rise and curve to create an abstract pyramid-like silhouette. The entire surface is covered in a vibrant gradient of rainbow hues, producing a dazzling visual effect that continuously shifts with changing light and viewing perspectives. From a distance, Pyramid Curbs appears as a monumental bundle of neon-colored roots emerging from the ground, while visitors approaching the structure discover it transforms into a walkable labyrinth where they can explore and lose themselves between the inflated walls.

True to Lancelin's artistic practice, the work successfully blurs the traditional boundaries between sculpture, architecture, and playground design. The installation employs repetition and variation of geometric modules to create a structure that manages to be both monumentally impressive and welcomingly approachable. The artist's vision celebrates community and joy, encouraging people of all ages to engage both physically and emotionally with the colorful creation.

The Return to the River festival provides the perfect backdrop for this urban intervention, as the event aims to reconnect Grand Rapids' downtown area with the waterfront through art, music, and public events. Within this context, Pyramid Curbs functions as both a distinctive landmark and a social gathering point, creating a unique meeting place where vibrant color, impressive scale, and innovative form merge together to completely reimagine how public spaces can feel and function for the community.
