Cell Shifting

The Cell Shifting Problem is to join copies of a polyform to construct two figures that differ in just one cell, with the different cells as near to each other as possible.

Polyominoes of order up through 6. Pentomino Pairs.
Tetromino-Pentomino Pairs. Pentahex Pairs.
Polyhexes of order up through 5. Hexahexes.
Heptominoes. Heptahexes.
Polyiamonds of order up through 7. Knight's-Move Cell Shifts for Polyominoes.
