From GenAI selfie to a 3D brand mosaic
A GenAI face-swap for Celebrate Consumer Care plus a gigapixel Three.js mosaic where hundreds of avatars form the logo, navigable in 3D.

For L'Oréal's Guardians program, we built two connected pieces. Celebrate Consumer Care, a Peoplesnap experience in English and French, renders each participant as one of four Guardians through a GenAI face-swap. The Guardians Mosaic then gathers hundreds of those avatars into a gigapixel mosaic of the L'Oréal logo, navigable in 3D: individual selfies become one collective brand wall.

Two scales: the phone and the lobby
L'Oréal's Guardians program called for two pieces at two scales. On the phone, a memorable Consumer Care activation in English and French, ready for internal events. In the room, a piece sized for event lobbies and private demos that would turn the Guardian community into a brand object. Both share the same cast: four Guardian archetypes in sci-fi suits.
From one selfie to hundreds of avatars
Celebrate Consumer Care runs on Peoplesnap, our photobooth product. The landing sets out three steps: select a Guardian, smile, share. The participant picks one of the four Guardians and takes a selfie, and our GenAI pipeline swaps their face onto the chosen character. The result is a brand avatar they can download and share, in English or French.
The Guardians Mosaic brings those avatars into a Three.js / WebGL app. Hundreds of them form a gigapixel mosaic of the L'Oréal logo, navigable in 3D from the whole logo down to a single face. Under the hood, a texture atlas packs the avatars together and shaders draw them on the GPU. Access is protected, for private demos and event lobbies.

Guardians Mosaic
Three.js piece: hundreds of face-swap avatars form a gigapixel L'Oréal logo mosaic, navigable in 3D, for private demos and event lobbies.
Every selfie, a tile in the wall
Both pieces are live. L'Oréal now has a bilingual face-swap experience ready for internal events, and a 3D mosaic ready to project in a lobby or open in a private demo. Participation is measurable, the user-generated content is of high quality, and the Guardian community has become a brand object.
