In this online meeting we will focus on the Seminar on the Generation of Plastic Forms (1969-1973).  These are the issues that we will address with three of its protagonists: the coordinator of the seminar, the philosopher and poet Ignacio Gómez de Liaño, and the visual artists José Luis Alexanco and Soledad Sevilla. The latter two participate in the exhibition with works created at this time and diverse documentation on their experiences during their time at the Computing Centre.
