Various people (was going to say several, but it is best not to exaggerate!) have asked for the link to the Prezi I used at the AISC conference in Hong Kong last week.
I have tarted it up a bit with a path that includes the bits I had to leave out and some more stuff a=in some of the stops.
You have to click on the graphic and go to Prezi because Worpress still doesn’t use the type of embedding that Prezi uses! Get it together guys!!
