An innovation that is reminiscent of scratch-n-sniff stickers of yesteryear, the Bouquet is a “synesthetic olfactory device” that essentially turns colors into smells. The cone-shaped invention is an ECAL project (from the Ecole cantonale d’art de Lausanne in Switzerland) by Erika Marthins, Arthur Moscatelli, Pietro Alberti, and Andrea Ramìrez Aburto. The user simply points the Bouquet and the device perceives the color, then sends a the corresponding fragrance (oftentimes a blend) to the user. To learn more, take a look at their video.
