I believe the locals name one Louis Wu. :)

Impressive! Is the "local landscape" a simple heightfield or an isosurface?

See you in Khyberspace!

LOL.

I've got Ringworld as a talking book. I must listen to it when driving 
to and from work.

Thank you indeed!

The local landscape is a patchwork macro of height_fields, thanks to John 
Van Sickle.

Thanks Bill!

The Rim Wall being so high, it "naturally" tends to loom even from far away. 
We are standing here about 99% across the ring (calculated from the center). 
So the Ring Wall still is about 5000 miles from the camera!

I wonder if it would really be visible so well, due to atmospheric haze and 
such? I think that Larry Niven has not really considered the question... On 
the other hand, the top of the wall is virtually out of the atmosphere, and 
we may be able to see better a long way up than a long way away...

The Rim Wall looms over the "local" landscape,, which is seen under an angle 
of 80 degrees to the Ringworld.

As Bill said: Louis Wu is the proper god. I wouldn't trust Nessus. ;-)

Well, the smart money would be on Nessus, but the locals never met him properly.

...and a possible (mid)night view would be like this one. Render time is 35 
minutes, mainly due to the water.

Yes, he is the hidden one, if not the hindmost... ;-)

Now that really is nice... a bit of light bloom and more opaque clouds would
make it almost perfect.

One thing has just struck me - I don't think the top of the wall would be
properly visible, especially at night. Since the top sticks out of the
atmosphere by some 800-900 miles, it should probably be obscured by the sky in
the same way as the arch, only showing up where in full sunlight. I don't know
how to make that look believable :\
