a set of "semi-abstract" circular visualizations of the WiFi encryption levels while traveling through the cities of London, Vescemont, Belfort & Barcelona. each circular item represent the recording of wireless network through a journey. each succesfull recording influences the time line thickness & adds a “pin”. red pins represent non-encrypted networks other networks are the smaller black ones. the thickness of the main line & the length of the "node pins" depends on the ecryption from thinner to thicker: "WEP" , "WPA", "TKIP" & "NONE".
