The document discusses how to integrate Rich Internet Applications (RIAs) and Smalltalk to create a "cute" or rich user experience application with a focus on visual interaction and intuitive interfaces. It proposes an architecture using a Smalltalk backend with a Flex front-end connected via SOAP web services. An example traffic jam simulator application is developed to demonstrate the benefits of combining RIA and Smalltalk, such as easier prototyping and richer user interaction, while also noting some potential shortcomings such as performance issues. The overall conclusion is that RIAs can be effectively connected to Smalltalk through web services to leverage the best of both worlds.
