Artists all over the world are sharing tributes to Belgium on Twitter with the hashtag #ArtistsForBelgium.

The image that is being used most  of the time is a “splatter-paint outline” of a Smurf in the colors of the Belgian flag. Others are using their own creativity.

According to Mashable, “The Smurfs are the creation of the late Belgian artist Peyo who debuted the small, blue creatures in the late 1950s and have since become a worldwide animation phenomenon.”
