Using commutators to solve the 3x3x3x3 (4D Rubik's Cube)

This video builds off of my introduction to the 3x3x3x3 to demonstrate how to find commutators to solve all of the pieces of this puzzle. These are not the shortest commutators possible but they are some of the most straight-forward because they nest within one-another building off of each other to solve the 2 then 3 then 4 color pieces. The software is Magic Cube 4D (MC4D) http://www.superliminal.com/cube/cube.htm
