Thank you Larry and Mark.

Love the image Ron, excellently rendered but I'm puzzled by the reflected? city-scape. If the ball has a window reflection, I guess it would be in a room and therefore the city-scape wouldn't be visible ?

So, if the ball were outside it couldn't reflect a window?

I would say not Ron. A reflection of a window is due to it being a light source. If the ball was outside a window wouldn't normally be a light source in my opinion.

Here's an interesting image of a crystal ball and how it makes the source behind it upside down

Let's assume that the ball is indeed looking at the buildings.
I think the buildings would be upside down.

Oops! Sorry, Egg. You already said that!

Cross posting Rick

Not only upside down but reversed left to right. Here's a good example. Note the balls are not only upside down but reversed left & right.

Final rendering.

I've been nearly blinded by light coming off a window outside...

But a crystal balls refraction would also work on the pen I believe Ron so the image would be more like this (apart from the window relection which is on the balls surface).

Edited image to show background of sky-scrapers. Like the new shading.
