La Fresque des Jardiniers
Sow virtual seeds and a fresco grows in real time. At the Cité des Sciences, built on fully in-house electronics.
"La Fresque des Jardiniers" is a collaborative interactive installation created for the "Jardiner" exhibition at the Cité des Sciences (2025-2026), in Paris. Visitors plant virtual seeds that grow in real time to bring forth, collectively, a poetic work. I handled all the electronics: the UWB tracking system (architecture, communication, anchors, gateways, battery management, embedded electronics), the design and assembly of the seed bombs, and the entire software stack. Its distinctive feature: no wifi at all, everything runs over UWB, processed by a Python system that computes the 3D position of the bombs, smooths it and projects it onto a hand-calibrated 2D screen before sending it to Unity for display.
Technical details
All the electronics are in-house: I programmed the UWB tracking system, its architecture and communication, the anchors, the gateways, the battery management and the embedded electronics, down to the design and assembly of the seed bombs. A distinctive choice: no wifi at all, everything runs over UWB. A gateway anchor connected to the computer sends data to a Python system that computes the 3D position of each bomb, smooths and interpolates it, then projects it onto a manually calibrated 2D screen. The 2D position and button state are then sent to Unity, which handles the drop, the throwing of seeds and the blooming of flowers.
