According to other artists in the smell art community, the Smeller does what no one else in the intervening time period has ever managed to do: it pumps a series of defined, distinct smells into the room, one after the next. The scents dissipate just as the next one arrives: horse, then cinnamon, and then something that reminded me of an underground car park. Different types of berry, in vibrato, one after the other. No sound, no visuals, just a scent, and then another, every inhalation a new surprise.
