"The project “Map” questions the red markers of the location based search engine Google Maps.

(...) While zooming in the map the pixel size of the markers on the screen always stay at the same size. But if their size is seen in relation to their environment they shrink while the user does zoom in the map. This effect corresponds exactly to the phenomenon of Mr. Turtur, the illusionary giant of the children fantasy novel “Jim Button and Luke the Engine Driver“ written by Michael Ende."

Check out the pictures and the movie by Aram Barthol.
