Exhibit 1: John Lennon and Yoko Ono.
Exhibit 2: Tsai Ming-liang.
Exhibit 3: Kiarostami
Exhibit 4: I love Mirror. Before DVDs, before YouTube, I tape the film for you as a gift. I have thought long and hard about what to give you that you will remember me by but I realise only later that what I really want is the gift of your face as I watch you watching the film.
