Hidden Rope Trick

Which rope is continuous from top to bottom? It may not be the one you think.

Use the slider tool (click or drag slider button) to make the vertical bar dissolve away. Were you correct?

If the ropes were aligned straight across it would be easy for us to pick out the continuous length. We are very good at linear tracking, but when the rope is steeply inclined, it is much harder to follow the correct path of either rope.
