This project targets riddle fans. Inspired from puzzling games, this project aims at reviving social physical interactions with brainteasers in theatrical “Folie imposée” (imposed craziness) scenarios. Placed in a public space this seemingly curious wooden box is not as easy to open as one would think. Communicating through a thermal printer, it pushes the user to solve the puzzles needed, go to the given locations and interact socially with the box in the aim of solving all the enigmas and finding out the contents of it. From rubbing to shaking to running around finding hidden spots, this box tests the limits of the user’s curiosity playing the role of a black box that never actually opens.
