nokia installed a giant arrow above london that pointed to places submitted through user's mobile phones.
the installation was part of nokia's effort to promote their navigation projects and was created by the
swedish advertising agency farfar. the arrow was set up next to london bridge and suspended from a large
crane. the arrow was outfitted with a large screen that could display locations submitted by users along
with their distance from the arrow and the user's name. not only would arrow display this info, but the
crane would rotate the arrow to point toward the location. users submitted the locations through their
mobiles or on nokia's website.
