Thanks Mod, I love that kinda stuff.
This one is slightly low quality...but it is awesome. I used to subscribe to digital blasphemy. (from whence it hails)

An image for us winterish folks. (just found it. To walk out your door...and see that.)
And..Larry Niven's Ringworld. A world with the surface area.. of 3.7 million earths.
People try to recreate the impression of such a thing..and they just can't quite get there. But one begins to get a glimpse, in the mind, of the sheer scale. But....the mind almost breaks. My knees get weak from just the thought of looking up into the sky...at that. It circles right around the sun.....
2 million kilometers wide, and 950 million kilometers long (around).
When you look at this, remember, to visit someone....it is not maybe 1000km, or even lets say, like flying to the other side of the planet. No..... 2 million km wide. (the wall is 1600km high) The feeling of insignificance and total connection..would be complete. Who says that science fiction has no soul? It would be burned into your existence, right from birth. In this 'shopped' image, imagine that when it finally takes shape out of the atmospheric clouding and cover, and comes up into definition due to it's curvature...we are talking about that point on the lowest horizon, being some good 2-2.5 million km's away. (!)
If one where to go the distance of 1/3rd of the way to the moon, straight up from the surface....and look down the rotational axis..it might look something like this:
Remember, that is 100,000km up from the surface. not feet, or meters...but 100k km.
In the book, there is an earth a 'replication' that was set up. Here it is, to scale.
