I wanted to try and see if I could make a copy of my own head. So with the aid of my wife and a garden chair and 123d catch I created this.

I tidied uo the mesh on MeshMixer by Autodesk and also melded it into a plinth I found on this site and HEY PRESTO! a museum bust.

Though to be honest the spectacles make me look a little like Dr Nefario from Despicable Me!
