This is exactly what electronic media artist Rafael Lozano-Hemmer is creating this November between Ciudad Ju\u00e1rez in Mexico and El Paso in Texas.<\/p>\n<p style=\"padding-left: 40px;\">Called Border Tuner, the project will see enormous bridges of light connecting the US-Mexico border for the first time.<\/p>\n<p style=\"padding-left: 40px;\">When lights from the stations (three on each side) are directed at each other and they manage to make a connection, a massive bridge of light is formed. This activates microphones and speakers allowing participants to communicate with one another across the border. The \u201clight bridge\u201d flickers like morse code as the participants listen and speak to one another. If they don\u2019t like what they are hearing they can retune to a different light beam.<\/p>\n<p style=\"padding-left: 40px;\">This is not the first time Rafael Lozano-Hemmer has used search lights in his art but he\u2019s never done anything on this scale or with this complexity before. Born in Mexico City in 1967, he first produced a remote-controlled searchlight project in 1999 for the Z\u00f3calo Square in Mexico City. Since then he has created installations in dozens of cities around the world where the public controls the searchlights using the internet, mobile phones, megaphones or heart rate sensors.<\/p>\n<p style=\"padding-left: 40px;\">Presented by Monica Ortiz Uribe<br \/>\nProduced by Emma Betteridge for the BBC World Service<\/p>\n<p style=\"text-align: center;\"><strong><a href=\"https:\/\/www.bbc.co.uk\/sounds\/play\/w3csz1zg\" target=\"_blank\" rel=\"noopener noreferrer\">Click here to listen via the BBC World Service.<\/a><\/strong><\/p>\n<\/blockquote>\n<p>Fascinating concept!
