Georg Heeg eK developed multimedia presentations for the Adventure World German Language exhibition at Köthen Castle in Germany using Smalltalk. The presentations included interactive displays on 42" touch monitors for visitors. The Smalltalk team created applications for the displays that were easy for all visitors to use without explanation and presented information attractively. The systems used a standard PC with two monitors - one for control and one as a touch display. A VisualWorks application managed the touchscreen canvas while content included websites, PowerPoints, and interactive games.
