Installation for the Design Forum held in Linz.

It was an experimental call about design from the thematic, historical, business, and personal perspectives of the creators themselves. Designers and artists such as Christopher Alexander, Rebecca Horn, Morris Lapidus, Sol LeWitt, Raymond Loewy, Mario Merz, Pentagram, Ettore Sottsass, and ourselves were invited. We took the opportunity to make a curious conceptual and economic reflection on the value of things. We titled it: "What can you enjoy for 10 pesetas a day?" and, in various showcases, we displayed about twenty different possibilities regarding this.

For example, with 10 pesetas (0.06 €) a day, it was possible, in 1980, to throw nine streamers, smoke two and a half cigarettes, rent 2 square meters of housing, or have a 100-watt light bulb on all day. You could also enjoy three trees, considering their purchase cost, depreciation, and maintenance. In another showcase, we reproduced an eighth of a cow, which was the portion of the animal you would get for 10 pesetas a day, considering its purchase price—12,000 pesetas—its lifespan—10 years—its depreciation—3.28 pesetas per day—and its maintenance—77 pesetas. (All these calculations were made by the then young economist Narcís Serra, who would later become the Vice President of the Spanish Government).

Each person, with their particularities, constantly decided in which everyday life option wanted to invest their money in. An intellectual game, an elegant joke, although difficult to conceive and convey to the public, which was concerning because I have always wished to be understood. In any case, the exhibition was beautiful, and visitors found it very "Spanish."
