hmm well i pilfered this link from newstoday…pretty strange and wonderful stuff from chinese artist LiWei

His first significant public exposure was at the Tbird Shanghai Biennale in 2000.During the opening ceremony, without any official invitation, he entered the gallery lobby to execute a performance piece. He showed up with a three -foot -square mirror with a hole, large enough to accommodate his head and neck. He places his head through the hole, his face reflected in the mirror. Looking at the mirror, his face seemed to be floating with the audience opposite, also reflected in the mirror. Viewers were surprised to find their images overlapping with the artist’s face. – Zhang Zhaohui
