As with Gandalf Arrives, the Attack on Weathertop has been depicted by several builders in recent years. Here are a few selections:
Here by Leaz
I like how Nathan included Gandalf's battle on Weathertop before Strider and the hobbits arrived.
Lord Amras includes a great detail - views of the Witch King both with the Ring off and the Ring on.
My own feeble effort (one of my first post-dark-ages MOCs).
I did include a view by Frodo while wearing the Ring. I was happy with this effect.
