The highlight of the collaboration was the space-saving[clarification needed] historical installation Lichtraum (Hommage à Fontana) by Mack, Piene, and Uecker, which was presented for the first time at the Documenta III 1964 exhibition.
The exhibition included large installations by Castellani, Gianni Colombo, Mack, Peeters, Piene, Soto, Tinguely, and Uecker.
