iPhone

Wind the key, lift the lid, and a porcelain ballerina turns to a lullaby. On iPhone Duo, your phone is the box: open it to play, close it to stop. Lullabox is a music box, made to feel like the real thing. Wind the brass key and the spring stores about a minute and a half of music. Lift the walnut lid and a porcelain ballerina rises in front of the mirror and turns while the cylinder plays. As the spring runs down, the music slows, just as it does on a real one. Let the lid fall and it shuts with a clack. DESIGNED FOR iPHONE DUO On iPhone Duo, the phone is the box. Closed, the outer display is the lid. Open it and the hinge becomes the hinge of the box: the mirror stands up and the velvet floor lies flat. The further you open it, the clearer the music gets. Close it and the music fades, then clacks shut. ON EVERY iPHONE The screen becomes the box. Lift the lid with your finger, or tap it, and it swings open in 3D. To shut it, let it fall or turn the phone face down. • Music synthesised in real time, so it follows the spring and the lid as they move • Watch the pins on the cylinder pluck the comb • Four public-domain melodies, including Brahms's Lullaby and Für Elise • No account, no ads, no data collected
