FILO
The wardrobe is the most public object in every home; everyone passes it, everyone uses it. FILO is an add-on that turns it into a place for private messages, delivered exactly where and when they're supposed to be heard.

Public space, private message
Household messages fail in both directions: notes on the fridge are public to every guest, and texts arrive at the wrong moment entirely. The goal was messages heard right at the moment of leaving or arriving, the moments they're about. Because the wardrobe is so public, privacy became the core design tension.
The keychain is the key
The answer was tangible: individual keychain hangers with distinct stencils that each person carries with their keys. Hanging your keychain is both identity and intent. Messages addressed to you find you, and only you, while the object on the rail stays perfectly ordinary.
A message is private not because it's encrypted, but because it arrives only for you, right where it was meant to be heard.
design intent
Prototyped until it belonged
Everyday objects were weighed before committing to the clothes rail. Then the housing was built for it: laser-cut MDF panels, 3D-printed listening horns and stenciled keychains, tested and mounted through iteration after iteration until it belonged there.
