The two of us for 24 hours


The exhibition Oui! opens doors and perspectives for couples with an adventurous spirit. This is not an exhibition in the classic sense, nor is it an interactive installation. The focus is on couples. And it is the couples who decide whether their visit to Expo.02 will turn into a memorable experience.

Meeting, finding one another, embarking on a common path - Oui brings a "me" and a "you" together: for the space of a day, two human beings affirm their feelings of sympathy for each other - to themselves and others. But how do you find each other? And how do you express your feelings? You are helped by the knowledge that nothing is impossible. Old love can be rejuvenated, new love strengthened. Or perhaps new and tender feelings can be tested and proved during this day in Yverdon-les-Bains.

The path embarked on by two people at the exhibition leads out onto the lake, beneath the filigree lightness and festive colour of the colonnade that encircles the long, plain building. Finally, they receive a shining confirmation of their mutual sympathy, a symbol and proclamation of their union - for 24 hours. It is up to each couple to decide whether what happens in the 24 hours after this remains secret or is made public.
