Attachment’ is a poetic machine which allows people to send digital messages, images or videos into the air attached to biodegradable balloons.

Attachment’s idea began as David Colombini’s diploma project at ECAL (University of Art and Design, Lausanne) in Media and Interaction Design in Spring 2014. In October 2014, the project got support from the Migros Culture Percentage (Grant fund for Digital Culture) to developp the final object. In  2016, the machine was finalized in collaboration with Thomas Grogan and the help of Niklas Hagemann. Since then the project has been exhibited several times in Europe.

Attachment’ is a poetic concept, a message in a bottle 2.0. Inspired by the rusty machines of Swiss sculptor Jean Tinguely, our fully automatic poetic machine will gives physical form to the digital message you send via our website.

First, It will engrave your message onto a thin piece of balsa wood connected by a string to a wooden clip. A balloon stock conveyor is then activated to place a balloon above a helium valve that automatically inflates it. Finally a simple two-piece wooden clip seals the balloon, which is then released into the air where it will travel haphazardly to a potential recipient.
