Enjoy!
1. Basic spiral.
2. My addition to the basic spiral. It makes a leaf shape that I like.
3. This combines two spirals and kind of looks like a ram's head when collapsed.
#3 Open
4. Long skinny trapezoid has more turns than the regular one.
5. This is a different spiral, based on Fuse's Naval shell with modifications by me.
6. Naval shell with a twist.
7 a & b. Variations on collapsing a spiral result in different effects.
7a is locked in the closed position. 7b opens into a complex corkscrew shape.
8. Note that in this sample the parallel lines are angles up slightly towards the center fold. This creates the openness in the center of the spiral. (see the picture below)
