I'd love to see a solution to my cube, both the 4x4x4 and 5x5x5 varieties of the wall/burr cubes. It definitely takes some effort to thoroughly mix the pieces. For example, the red/orange and blue/green faces tend to stay together, but they can be intermixed. It's also possible to flip the white/yellow parts as well. I can also easily transform between the wall/burr brick formations intuitively, disregarding the proper color matching of the bricks. The symmetry between the 4x4x4 and 5x5x5 cubes are similar, but they behave a little different due to the odd and even layers. I believe the 4x4x4 variety can in some ways be a subset of the 5x5x5, so a master solution could possibly be applied to both cube types, like how professor cube algorithms mostly work on the master cube.
Please, if you have solutions, feel free to share them! Bonus points if they're easy to follow. My 4x4x4 and 5x5x5 have remained scrambled since shortly after removing them from the box.
