This journey predates several of the zooming capabilities developed more than 60 years later in virtual globes. First, it integrates the combination of the spinning globe with a zoom effect on a specific point. Second, it uses a similar ‘jump’ effect as the one currently available in Google Earth to move from one place to another. In this case, the journey from Paris to Casablanca starts with a zoom in on Paris, followed by a zoom out moving toward Southern Europe, then a zoom in to Morocco and finally Casablanca. The jump effect is very compelling as it simultaneously follows the journey from Paris to Casablanca being traced on the map. Third, the perspective changes from 90 degree view of the cartographic representation of the world, to an oblique perspective of the streets of Casablanca and resonates with the recent development of street views functionalities in applications such as Google Map.’
