Matjaz Valentar the designer behind Webshock shared a beautiful motion design project. Titled Animations 2019 - Set 1, the post is a collection of animations featuring themes ranging from typography to more abstract and geometric forms. All of them are done in 3D, which makes me want to learn how to use 3D tools like Cinema 4D. Personally I love the simple animation of cubes and spheres that Matjaz has here, perhaps, trying to recreate some of those might be a good motivation for me to learn 3D.
