The project
An anniversary greeting turned into a pop-up object. Archicercle made a cake prototype for a customer-facing advertising campaign, intended to surprise recipients as they opened the piece.
The interaction begins with a simple gesture: taking a flyer out of its envelope. This triggers the cake’s automatic unfolding mechanism, powered by elastic bands housed inside. The mechanism is part of the tenth-anniversary greeting itself.
The studio’s documented contribution was making the prototype with this opening system. The piece gives physical form to the promotional proposal through an object that changes configuration as it opens.
The prototype takes the form of a white, two-tier cake made up of stacked cylindrical volumes. Flat cut-out elements, bow motifs and a greeting card accompany the assembled piece, placing the pop-up structure within the proposal’s wider graphic composition.
Internal elastic bands power the unfolding action, triggered by removing the flyer from its envelope.
