Chester 4x4 Halfish Cube

First 4x4 shape mod.

Not sure what I expected being a 4x4 mod. All the joys of a 4x4 parity coupled with the shape mod aspects makes it something not for the faint of heart. Turns very well. I really enjoy it.

An Intense Challenge Even for the Experienced

This cube, which is mechanically identical to a regular 4x4x4, is tricky to operate because the 2nd and 4th layers must be 1/8 of a turn for the cube to function. All the same algorithms apply - except for how to restore the centers when you apply an opposite edge pair exchange sequence.
