Thanks to Simone Di Santi, who interviewed me last year in Florence, Italy, while I was streetpainting. Simone and her partner create a travel video Web series called "A Road Retraveled".
Please note that near the end of the video when they are scanning the young nude Giovanni (St. John) by Caravaggio: This part of the video clip was taken AFTER the street cleaners (vehicle) passed over it the morning after it was drawn.
