At SwarmSketch you can collaboratively sketch with other users, from all over the world,  on an online sketch board. A new – popular search – term is randomly chosen every week, which becomes the sketch subject of the week. Users have the opportunity to sketch one line which adds up to what others have already drawn. The sketch grows thanks to the contribution of all users.

Furthermore, after drawing a line, a user can improve the sketch by regulating the color of the lines drawn by other people, which the system randomly choses. Another interesting feature is watching an animation of the progress: how the sketch evolved during the week.
