I would disagree that programming is the only interactive art form. Drawing and painting are quite interactive when you take into consideration the interpretation that the audience must perform, and, more importantly, the back and forth of artists as they see and react to each other's work with their own work.
In that sense programming is very much like the visual arts.
For what it's worth, I've been visual artist for around 40 years and a programmer for around 35.
First thing that came to mind for me was various forms of sculpture that interact with people. Not far from where I work there's a shopping center with fountains right in the floor in the middle of a little plaza, but they turn off when people come close. I know there are other (better) examples. And that's not even getting into performing arts.
