It was the 2010 South African World Cup and german magazine AIT decided to launch Project "Xhosa" Charity Chair, which consisted on the re-designing of Matthias Weber´s ONO chair, initiative followed by 120 european architects and designers.
The re-designed chairs were sold in an auction in Berlin that year and the profits obtained supported the Guga S´Thebe cultural centre and AIDS orphanage in the Langa Township in Cape Town, South Africa.

The patterns used for the perforations were inspired by those used in traditional Xhosa face painting still widely used. 
The chairs were exhibited in a travelling exhibition in Munich, Hamburg, London, Rotterdam and Kortrijk.
