 Popper also has had many personal encounters in Paris with Groupe de Recherche d’Art Visual, Carlos Cruz-Diez, Yaacov Agam, Jesus-Rafael Soto and Victor Vasarely which proved to have had a substantial impact on his view of art and art history.Following this inclination he took interest in the works of Piotr Kowalski, Roy Ascott and many others working with the early concept of networking.These artists confirmed his interest in spectator participation, which brought him to the late 1980s and the 1990s when immersive virtual reality and digital art began to become established.
