Hi Hannes,

There were no PowerPoint slides. A last minute change to the talk was to 
move the slides to persistent workspaces in the demo image.

This change was not captured in the image I posted before going to 
Cambridge.  The post is now updated:

The first slide is the top of the PersistentWorkspace named 'Introduction'.
The second slide is at the bottom of that workspace.
The demo program is in the colored window. There are 3 yellowbutton 
commands (use cases)
     'animate shapes' - objects come and go
     'animate roles' - animates the message flows of the repeated 
execution of  some use case. All flows have the same topology.
             ALT-1 traces object ids. ALT-2 adds class names . ALT-3 
adds role names.
     'animate chaos arrows' animates message flows with no common 
topology. DCI has nothing to offer for such executions.

TheWorldMenu>>open...>>BB5BankTransfer runs a very simple demo of the 
DCI concepts.
