How to Fold Eternally Opening Origami

Here is a delightful origami project. This may seem to experienced folders to be very similar to the 'Bird Base', and it is. It only needed someone to some the addictive dance it can do.

1. Start with a square sheet of paper. The front of your paper (the side you want to show in the end) corresponds to the blue side of the paper in the photo. The hidden back of the paper is white in the photo.
   
   
2. Fold the sheet in half, into a rectangle. Be sure to crisply crease your folds.
   
   
3. Unfold, and fold in half the other way.
   
   
4. Unfold your rectangle. Turn the paper over and fold in half into a triangle. You should see the back of your paper. Unfold and repeat along the other diagonal.
   
   
5. Unfold your paper and turn it back over. You should see the diagonal creases create "valleys" and the perpendicular creases create "mountains".
   
   
6. Bring the corners together. Allow the valley creases to come together in the middle.
   
   
7. Align the square. By flattening two opposite sides, you should find yourself with a square that is open on the bottom. Make sure your square is rotated so that the opening is on the bottom, as shown in the picture.
   
   
8. Bring the right corner of the top flap to the middle crease, so that the lower right edge lines up with the crease.
   
   
9. Repeat this action on the left, so that the top looks like a kite.
   
   
10. Fold down the top corner to make the crease lie along the horizontal line created in the previous two steps.
    
    
11. Unfold. In doing so, you return to having a square with an opening facing down.
    
    
12. Take the bottom corner of the square and start to fold it up along the horizontal crease you made in the previous two steps.
    
    
13. As you fold, notice the four diagonal creases on the inside that you made earlier. You will need to reverse the two creases on the upper flap. To reverse a crease, fold it in the opposite direction that it naturally folds.
    
    
14. Bring the outer edges to the middle and flatten, so that you have a diamond.
    
    
15. Turn your paper over, and repeat the previous five steps.
    
    
16. Congratulations you have the Eternally opening origami completed!
    
    
17. Now, take the two "legs" (the parts that would have become the head and tail if you were to continue to a crane or bird) and grasp them two-thirds of the way up and pull them away from each other.
    
    
18. If you did this correctly, the parts should reverse their orientation and you could repeat this on the lower section (now the top).
    
    
19. Finished.
