Using the travel data from the art project The Location of I, by Martin J Callanan this aquarium below was generated. Again the Google Earth Plug-In is used to visualise the KML file. The file can be downloaded here, on the website of the artist, tweaking is done in excel. The time data is recalculated as the height information. Therefore the altitude represents the time.
Other visualisations of this type have been tested here before and can be found here.
