The Making of Humongous Street Art!

I see this kind of art diving up everywhere in various cities spread across different countries. These huge paintings covering one entire wall of a building. The one more beautiful than the other. Still I always wondered how they would be making such art, which is exactly what this video prevails.

Continue to make such art, it lightens up even the worse parts of a city and they continue to make my day each time I see one.
