Cobble
Cobble is a Bluetooth bookshelf speaker with an interactive interface on the top surface. Four magnetic pegs can be placed in different patterns on a grid. When a preset pattern is completed, the speaker plays a saved sound profile, such as a nature or white noise loop. Cobble also works as a normal Bluetooth speaker for audio from a connected device. The placing of pegs recalls the board game Go and invites a short moment of quiet concentration. The prototype uses a wooden casing, sand-blasted acrylic panels and LED light strips.
