DIALOGUE is a large-scale light art installation by artist Christopher Bauder commissioned by Royal Commission for Riyadh City for Noor Riyadh Light Art Festival 2023. The city-wide show transforms two of the most iconic towers on the Riyadh skyline into living characters that interact with each other and communicate through light and sound. The towers send light signals as a non-verbal exchange to express abstract emotions. Sometimes they appear friendly and playful, sometimes curious and inquisitive, sometimes angry or frustrated.
