I realize that we often highlight outdoor in our monthly good media ideas, but there's a lot of room for innovation & creativity in this space. This month's idea is a fun one that really only works in the city that it's been done - Seattle. The idea is something that Media Post calls "Rainvertising," and was executed by agency Publicis Seattle. To promote a local music & arts festival Bumbershoot, the ad campaign called for the use of a rain-activated paint called NeverWet that only comes visible when wet. They painted the streets and sidewalks of the city with clever tags and promos related to the festival and rain. Watch below video for a full video of how they pulled this off. 

We like this idea because it's a unique idea that fits the city and culture; it's not just creative for creative's sake though - it fits the event it is promoting as well. It creates a new medium and that medium furthers the message excellently.
