When looking at the demo, what do the red lines/ dot represent? The lighter green lines represent some other point in space, and where on the retinas that point in space would land. On one eye in the demo, you see a darker green line. What does that darker green line represent (Hint: notice what happens to the light and dark green lines on the top retina when the point lands on the horoptor)?
