For the projection aspect, a San Diego company called AV Concepts used a variation of avisualeffect that was discovered in the 19th century, known as Pepper's Ghost.
The result is, in effect, avisual journal, with Kiarostami himself and his associate toting cameras and filming each other at work on location, as if to filter the report through an understanding of who he is and where he comes from.
The unintended side effect is that the extra visual detail gives the entire film a sickly sheen of fakeness: the props look embarrassingly proppy and the rubber noses look a great deal more rubbery than nosey.
