Okay. How about a new primitive? (I /think/ it's new, but of course there's nothing new under the sun so I might be mistaken.)
Take 8 consecutive bytes, imagine them as a square of 8x8 bits, and 'tumbleweed' the bits clockwise.
That is, turn this:
      abcdefgh
      ijklmnop
      qrstuvwx
      yzABCDEF
      GHIJKLMN
      OPQRSTUV
      WXYZ0123
      456789+=
to this:
      4WOGyqia
      5XPHzrjb
      6YQIAskc
      7ZRJBtld
      80SKCume
      91TLDvnf
      +2UMEwog
      =3VNFxph
The inverse is of course to tumbleweed them anticlockwise.
Sort of gives a new spin to bit rotation.
