Superellipse or deform a grid into a circle in Blender

I enjoyed working on this superellipse node group. It deforms a grid or circle into interesting shapes. Check out my tutorial. I explained the process step by step (I tried to keep the math down).

Here’s a link to the tutorial: https://youtu.be/gbfrpSlueVw

You can get the free node group here: nmesomtochukwu.gumroad.com/l/ebgpgu or from my Google Drive: drive.google.com/file/d/1IiISRLswKSSPctvmRvVNAduB25FlkAId/view?usp=sharing

One good thing about this node group is that it maintains perfect topology even at close extreme exponents.
