Grains of sand blowing in the wind

Wooster Collective spotted the work of artist Jorge Rodriguez who draws huge illustrations onto the side of Madrid buildings. The amazing part is that the wind and rain removes them. I have never been able to understand how artists can translate this from head to reality. Its so massive on a scale; how can they know what each brick should have. This guy is on a crane and it blows away?!@# Tragically beautiful.
Wow
