Gio Ponti, ‘Parete Organizzata’ illuminated wall organizer, 1950. "Italian architect Gio Ponti’s illuminated wall organizer would normally be categorized as Design, primarily due to the fact it has an obvious function, whereas, curiously, Kazimir Malevich’s design for a ceiling, in spite of the fact that it too has a function, is normally categorized as Art. Flat Art is normally hung on the wall; Design rarely is."
