I could not understand. What was the bar cutout width and was the remaining bars the same width? The smaller the gid the more the movement is better? Could the pictures be created on a computer? Sure could make a lot just selling pictures to print! Could the head and bill be animated for more movements? How about a plastic panel to last longer. Another idea is 3D printing the slotted cover? That sure would be nice and I could try printing given the dimensions. Anyone post that info?
