The Museum of Feelings doesn't really have “exhibits" in the conventional sense; rather, visitors move from one themed alcove to another, five in total, each with its own distinctive aroma. The “Optimistic Room," bathed in vivid pink and purple light, is little more than a lightshow, with patrons using small reflective panels to bounce light around the room. An attendant tells me the odor I smell is “Radiant Berries." The “Joyful Room" is a dense jungle of green LED lights suspended in vine-like plastic tubes; the “Invigorated Room" encircles visitors in halos of bright light projected on the floor that respond to their movements. The “Exhilarated Room" is a funhouse of crystalline mirrors, like Superman's Fortress of Solitude, dotted with flower-like patterns and accompanied by the putrid odor. The “Calm Room" is like stepping into a cloud, saturating us with a fine mist of “Vanilla and Lavender".
