There are two clear front runners for most important visual storytelling method: the emoji and the GIF. In the case of the latter it’s becomes increasingly interesting to see how people are experimenting with the media of short, looping animations. One of the most impressive artists I’ve come across lately is designer and illustrator Drew Tyndall, a Nashville resident who has created some impressive looking GIFs that are reminiscent of Sol Lewitt mashed with Piet Mondrian. His ability to create such fluidity and texture in each of these is mighty impressive, and his color choices are absolutely spot on.
You can see more of his looping illustrations in his portfolio.
