@rosborne979,
I was actually working on this a little. It would be an interesting setting for a science fiction story.
Obviously if you stood on the edge of the disk (i.e. the side of the disk), gravity would be pulling you toward the center. You would walk horizontally compared to someone at the center. Near the edges, you would feel that you were on the side of a very steep mountain since gravity would be pulling you, mostly horizontally, toward the center.
I might write this story.
