The project proposes different models of objects. Some of them are produced in large amount, while others are unique. They display different kinds of behaviors through the use of simple sensors and emitters (e.g. light-sensor, distance sensor, microphone, LED, speaker, LED display, etc). Objects produced as part of Accrochages should ultimately be auto-sufficient (ie. able to recharge themselves, with solar panels for instance) and low-cost (less than 15 Euros).
