System dynamic models are tools that allow one to explore the quantitative behavior of systems through time. However, real systems are usually multidimensional with both quantitative and qualitative variables. Recent development in digital video and sound processing suggest the enhancement of system dynamics models with streams of images and sounds related to the systems those models try to represent. A framework to integrate systems dynamics modelling and multimedia technologies is proposed herein. A multimedia systems dynamics water pollution model is included for illustrative purposes.
