“Chronoshelves” is an interactive display and quizz of chronological data.
Time units are represented by named and colored drawers, which can be dragged around. Time is represented (not to scale) as shelving, where shelves on top of one another represent consecutive time periods. There can also be vertical shelves to the left, which represent “macro” units, containing an arbitrary (and possibly nested) number of subdivisions.
The drawers start in random positions outside the shelves, and the user has to drag and drop them in the correct place. A score can then be computed, and incorrectly placed drawers marked.
