One thing I find really cool is when 3D artists practice their skills doing little balls of various materials.
Guillaume Kurkdjian, a French designer, comes up with fascinating 3D animations. He's got a sweet style which gets you right on arrival and by the end you'll need more! These are the kind of animations that fit perfectly as decoration in a website, and I would love to have some of these in my next project!
For more of Guillaume's work, please visit his Instagram account! He's got plenty more examples of his work there! I hope you enjoy these! Cheers. ;)
