I had the opportunity to collaborate with my colleague and friend Mathilde Veuthey, who led the art direction on this project. The brief was to design the key visual for Electron Festival 2025, Geneva's largest electronic music event. The concept: a heart orbiting like a free electron. Achieving an airbrush-style iridescent finish in 3D was a real challenge — I eventually solved it by exporting each trail individually and doing the colorization and compositing in After Effects.
