Sorry, what do you mean by motion and expanding numbers?

There are only 4 actions in this puzzle: expand to left, expand to right, expand up and expand bottom (and U for undo)

Here is version where you can also use W-A-S-D instead. http://jsfiddle.net/h2yJn/2966/embedded/result/

Also, if you manage to solve this puzzle, don't hesitate to post back on how you did it :) (e.g. pastebin the list of actions that is below the grid)
