The source

A Greek column stood on an abandoned parking lot near a big DIY store on the outskirts of Berlin. From a distance it looked as if it was carved out of pinkish sandstone, but it was made from a cloth with a sandy structure and color. Soon water started trickling from underneath it, forming a small puddle. The column then started moving slowly, thus using the water to draw lines and shapes on the hot tarmac. After the source ran dry, the column froze again and later on disappeared. Duration 30 minutes.
