I have a web application that can submit a simulation job, and display the results. Once the results are displayed, it has a reset button that can reset the data conditions to what it was before the simulation ran. There are no inputs to be taken from the user, but the simulation exercise has to be explained (quite a basic scenario). The results contain some tabular data and a couple of graphs. The simulation takes about a minute, so while that minute is in progress, the app can inform the user about the various benefits of our product, potentially through a set of animated graphics.
