Laura, That is pretty slick. If you are using a large mouse pointer, the OS will give you a large Not Allowed (red circle with slash) symbol. If using an inverse mouse pointer (black mouse), the Not Allowed is a black circle with slash. The areas within the circle are "see through" -- you can see the content behind the circle and slash within the circle. Another option would be to have no cursor at all [disabled] { cursor: none; } which i noticed immediately when trying to point at a disabled control and the pointer disappeared.
