Mural painting - Mixed Media graffiti
 

I found this video and thought it was cool to watch the painting of a huge mural...this is called mixed media graffiti.

it's cool, but it's more like mixed styles than mixed media. in general, mixed media art means using multiple materials (paint, chalk, torn paper, etc.). This is all paint

Technically this is true. However, on many occasion artists have used the term "mixed media" when they A) either do not want people to know what they use when they make soemthing or B) want more attention than the guy who is just claiming 'paint'. Considering he is using a wall to hold the paint it could be considered mixed media like nearly any other form of art.
