That's not really the same shape at all. There is little fluidity in the way the stones are set out - it's like a teenager playing an electric guitar badly, fingers jammed over the keys. I have a name for this shape (but it belongs in Frank Zappa's song Bobby Brown better). For the aesthetics of this container form please see Bernard Leach 'A Potter's Book'. Better still please, someone buy a paperback copy, give it to Goldsworthy "I think you should read this before you go any further". I offered to teach him to wall once - never got a reply. We go back to Stonehenge (June 21 1972).
