Maria Ambamovic:

The Artist is Present was a 2010 piece (MOMA) where Maria Ambamovic sat in a red dress and stared into the eyes of 1,000 strangers. Each time she would close her eyes after and would open them for the next. On this moment, she opens her eyes and unexpectantly is staring into the soul
of her ex-husband. It is a beautiful moment as you can feel everything they are thinking without either saying a single word. You feel sorrow, loss, and love. Ironically he ended up suing her 5 years later over not being credited for joint work.
