Airbnb's Walls and Chains is a story about the Berlin wall and the effects it had on the people who guarded it. Now looking at the animation it is pretty clear that it is hand drawn, but here's the thing: it isn't. This is a semi-new style known as non-photorealistic rendering (NPR). NPR is a style that uses 3D models to create a the feel of hand-drawn landscapes. It might seem impossible at first but with new innovations in technology it's actually forecast effective and easier than the standard CGI characters that make an appearance in every major move now a days. Walls and Chains is a great example of how flashing and extreme animation is not needed to tell a emotional and developed story.
