Internet-of-Things answering machine from 1992, with marbles

Durrell Bishop's 1992 grad project for his design program at the Royal College of Art was a brilliantly conceived riff on the answering machine, making use of physical, legible interfaces that made a point of exposing the conceptual workings of the device to its users.

Durrell Bishop is a partner in Luckybite with Tom Hulbert, working on physical interfaces, product design and interactive media. Prior to this he was a senior interaction designer at IDEO Europe. He co-founded Itch, which won a D&AD Gold award for large-scale work on the Science Museum Welcome Wing, and he was a partner in Dancing Dog, working on camera-based interfaces to computer games.
