Sea World

That sounds like a good, logical explanation, especially since your screen is actually a vertical surface in front of you. I interestingly enough didn't have a problem with this map's orientation, even though I am prone to it with photographs of the moon's or martian surface. Maybe a more asymetrical shadow, that is, one that is longer due to a lower angle of the sun, would help? That way, it should be easier to see that the shadows are on the surface, and not on an inside wall.

Oh heck. For me it is the whole Two Faces or a Vase thing. One second I see two faces, the next second I see a vase. My vision has slipped over the last few years, so it takes me a few seconds to focus. Not sure that extending the shadows would necessarily help me, but it might help others.
