Interactive work based on the book of the same name by Italo Calvino. In 1984, he was invited to deliver a cycle of lectures at Harvard University in the United States. The writer elected six themes: lightness, rapidity, exactitude, multiplicity and consistency. Calvino has written the first five, but died before the completion of the last. The conferences never took place, but the texts were collected in a book that serves as an important inheritance to the newly-born millenium.
