Hi everyone!
I am currently writing my bachelor thesis. Therefore I am looking for a very specific kind of street art and I would love to get some tips and suggestions.
Does anyone know street art where the recipient is asked to participate?

My Examples:
- The John Lennon Wall https://prag.sehenswuerdigkeiten-online.de/sehenswuerdigkeiten/john-lennon-mauer.html
- "Face2Face" by JR https://www.jr-art.net/projects/israel-palestine
- "Women are heroes" by JR https://www.jr-art.net/project-list/woman-are-heroes
- "Before I die" by unknown https://twistedsifter.com/2012/07/before-i-die-i-want-to-street-art-project-candy-chang/

Thanks in advance!
