    On 4 November 1984, a festive interment took place at the spot where Groddeck's 
    hut used to be. Eberhard Eckerle lowered his metal sculpture Buch vom Es with 
    air-hole into the earth inside a casket painted by Alphonso Hüppi. Each 
    of the participants then placed a stone on the buried objects. Today, visitors 
    are also encouraged to heap stones on the 'It-Point', the aim being to create 
    a pyramid above the air-hole.
