I find infill patterns to be more and more interesting and beautiful in slicer software over time but unfortunately it's often hidden within the perimeters of a closed 3D printed part. I wanted to use an infill pattern to create a lamp above the eating table since it still needed one. In particular the gyroid pattern is pretty cool in the way it's build up.
