Three artworks. One gesture vocabulary โ€” โœŠ fist, ๐Ÿ– open palm, โœŒ๏ธ victory sign. Completely different experiences.


โœŠ ๐Ÿ– โœŒ๏ธ Rock-Paper-Scissors

Not a game you play against someone. A living ecosystem you set in motion.

Make a gesture and a 3D object โ€” a rockโœŠ, a sheet of paper๐Ÿ–, a pair of scissorsโœŒ๏ธ โ€” spawns at your hand's position and is released into the scene. From that point it's on its own. Step closer to the screen and your objects spawn larger; step back and they spawn smaller โ€” depth is part of the game.

Objects flock with others of their type and hunt the type they can defeat. The screen fills with competing swarms, shifting and regrouping as new gestures arrive. Watch your scissors chase the paper someone else just spawned. No two sessions look the same.


๐ŸŒธ Bloom

The quiet one.

๐Ÿ– Each hand summons a bee that follows your movement through space. Hold still for a moment and a lily grows where you paused โ€” a permanent mark of where you were, varying in size, organic in feel. Move closer to the camera and the bee gets larger; further away and it grows smaller, as if receding into the distance.

Multiple people interact at once but the experience feels personal. Your bee. Your lily. Your corner of the screen.

Bloom extends the original Lily artwork from the 2025 Reflexions installation.


๐Ÿซง Lavalamp

Lavalamp is a fluid particle simulation โ€” 65,536 particles moving together, forming colourful shifting blobs that give the screen the hypnotic quality of a lava lamp.

โœŠ A fist pulls particles inward like a gravity well.

๐Ÿ– An open palm pushes them away like a gust of wind.

The closer your hand is to the camera, the stronger the force โ€” step forward to pull or push harder, step back to ease off. With multiple people interacting, competing forces tear the simulation in different directions at once. Every gesture leaves a trace that slowly fades.

Lavalamp extends the original Water artwork from the 2025 Reflexions installation.
