These are screenshots of the PlaySpace in use. The user is creating a model of events and temporal relations surrounding the Salem Witch Trials.
1. Here, the user has created a simple timeline meant to model a small sequence of witchcraft accusations. Notice that each point or event is color-coded and labelled, and that the entire timeline has been placed on a single translucent layer titled "accusations."
2. Three more timelines, each on separate layers, have been created. These model full moons and lunar cycles and the relative frequency of sermons on witchcraft preached in Salem Village. The scholar is making use of the "Inspector" tool to label, configure, and color-code his models.
3. Here, five timelines have been created, and the user has linked them for graphic manipulation by clicking the "link" icon on the layer tabs at the bottom of the screen. Now any manipulation of the view tools in the bottom bar (including graphical and granularity zooms, panning, snapping to center, and translucency adjustment) will apply to all linked layers. Notice that some lines have been zoomed separately, so that they now extend beyond the borders of the stage. The "Temporal Objects" menu is pulled down, allowing the user to add additional lines, points, events, or intervals, which would then be configured in the Inspector.
4. This final screenshot shows a zoomed-out view of the lines, which demonstrates the visual capacity of the PlaySpace to contain a large amount of data. The user has opened the "Inflections" menu, and is beginning to experiment with subjective and interpretive transformations of his model. Inflections such as "Foreshadowing" are most useful for literary subjects, while markers like "Causality" prove useful in a number of contexts. Eventually, the PlaySpace will support user-created inflections much in the same way it now permits users to create their own graphical legends for PlaySpace models.
