The idea is to teach the child about the concept of topography as a mapping technique by expanding the two dimensional elements in the style of a fin model, allowing them to see the same object in both 2 dimensions and 3 dimensions. The illustrated explosion is a nod to the volatility of volcanoes and the history of Mount Vesuvius itself.
