How can I take a color image, divide it into a 2x4 matrix, and shuffle those areas to output a scrambled image?

I have a 769x1024 image and have made panes that are each 383x255. I want to rearrange these panes so that is outputs a scrambled image. For example, if the panes are named [A B C D; E F G H] I want it to scramble to something like [B D F G; C H A E], but with a different output each time.

mat2cell(), and randperm() and reshape() to create the indices, create a new cell by indexing the cell output by mat2cell(), and then cell2mat() to create the new array.
