A meditative falling-sand toy that doubles as a generative instrument. Pour coloured sand, water, fire, and seeds into a glass vessel and watch them fall, pile, and avalanche — and because every grain that settles plays a note, building your sand-art bottle quietly composes its own ambient music. Tilt to pour, swap palettes, vessels, and soundpacks, or just leave it be and let the scene drift.
