30 shoelaces dyed with indigo and urine of thirty different people.
The sculpture called 'Personalised Shoelaces' started as a workshop where one could dye shoelaces with his, or her own urine and indigo. The urine contributions were collected in labeled jars, one month before the workshop took place. After fermentation, the same donors could dye shoelaces with their own urine. The workshop took place at Fort Gorgast between Berlin and the Polish border in summer 2015, thanks to the generous support of O Tannenbaum institute and thirty urine donors.
