That's a really cool side. Sad that it doesn't allow duplicate indices. I tried implementing the same thing but with support for duplicates and it was definitely a humbling exercise. I'm curious if there is any formal mathematical theory for this (shifted-off bits would probably make it less elegant than pure rotation)
