Thanks for the link, that's brilliant. I've been watching the slow development of one of these murals on a walking path near me. Maybe I should start taking my own photos to see if I can get a timelapse.
“The Subconscious Art of Graffiti Removal” is a tongue-in-cheek documentary short film with a similar take on the art of graffiti removal. The filmmaker interviews Portland city workers about the process and follows them on their day painting over graffiti. The film is available on YouTube.
