As per this article, Wolfgang Georgsdorf has focused on creating olfactory art, culminating with the "Smeller 2.0," a gigantic contraption the size of a small room that allows fragrances to be played like the keys of an organ or a piano.
Funnily enough, the idea of movies having a smell sense component is not a new one:
In 1906, before movie theaters even began to use sound, a newsreel of
the annual Rose Parade in Pasadena, CA was shown in a theater in
Pennsylvania, with electric fans blowing the scent of the flower through
huge cotton pads into the audience.
Where Georgsdorf hopes to avoid the mistakes that previous innovators have made in the field like Aromarama is through making sure that air circulates quickly and efficiently to prevent odors lingering and becoming overpowering.
You can experience the Smeller 2.0 at Berlin’s Martin-Gropius Bau museum. Would you go?
