Sample code used in Camp Smalltalk London 17/7/2010 to teach Smalltalk.
The code is a small Seaside app which takes a live feed of transport data http://www.highways.gov.uk/rssfeed/SouthEast.xml, parses the data and provides a number of different renderers. The aim isn't to teach Seaside, more for new to Smalltalk developers to create loops, inspect values and change code in the debugger, hopefully giving a rapid feeling of progression
