Daniel Pascal, also known as kinpraw, made himself a birthday present in Blender in the form of a Mario scene. There, he meets the brothers surrounded by familiar coins, a green pipe, and a box waiting to be bumped.
According to the caption, the plasticine-looking project was created with Rahul Parihar's Clay Doh shader, which makes 3D objects seem hand-made.
If you want to see what kinpraw does outside his birthday, welcome to his X/Twitter, there are lots of cool stylized projects.
