There are some projects that are simply hard to describe how awesome they are. The Classic. Typefaces by Particle (Gao Yang) is one of those memorable 3D and typography posts.
Mehmet Özdemir shared a set of beautiful 3D compositions titled Shapes. These images have simple forms and shapes like spheres and cylinders using materials such as glass and matte colors. The beauty is in the color palette, the movement of each scene as well as the realistic light and rendering. All of that using Blender, my favorite 3D tool.
