Many of you will remember the scenes of the giant machines wandering around old Portobello High School, progressively tearing larger and larger chunks out of the building. There was something of the tyrannosaurus about them so it was a flash back this morning to see this one rearing into the sky. No blood-curdling scream but a gentle flow of concrete emerged and has continued all day. The machine arrived at 6.45 this morning, with its long tentacle all wound up on itself in Duddingston Park ready to build anew.
