Cone or Tunnel?

This picture looks like a series of circles, getting smaller towards the center.

Drag the center of the circle in any direction to change the pattern. When you change the pattern it can represent more than one thing. For an example, are you looking down a long tunnel? Or at a cone shape?

Try dragging the pattern into different positions. It's fun!
