Challenge Conveyor Puzzle

All the number from each of the four directions from the center are linked and rotate like a conveyor belt (each 2x4 block of number along each edge). Arrange the numbers so that they appear in order from the top left (starting at 1) across each row before going down to the next row, ending at lower right (ending at 16).

CONTROLS:
Use the mouse, drag-n-drop style, to direct any number vertically or horizontally. The direction moved will be the major length of the conveyor.

Press 'r' to randomly mix the puzzle.
