2D to 3D: What's Going On? (Part 2)

In the app below, the 2D figure you see on the left is the same as the 2D figure you see on the right. You can move the LARGE POINTS around to create different 2D figures.
Move the points around and fully slide the slider to create a very simple geometric surface.
