French artist Armelle Caron uses maps in a couple of ways. First, have a look at her organized city maps, executed between 2005 and 2008, in which city blocks are taken apart and organized into neat rows. She does something similar with a world map in Le monde rangé, available as a poster. See also her 2010 series, Les villes en creux, where city blocks are cut out of the paper. Nice effect.
