[In 1988, Ulay and Abramović decided to make a spiritual journey which would end their relationship. Each of them walked the Great Wall of China, starting from the two opposite ends and meeting in the middle. Ulay started from the Gobi Desert and Abramović from the Yellow Sea. After each of them walked 2500 km, they met in the middle and said “good-bye”.] [via]
