It would be cool to have it do different things based on the game.
The Palantir can be lit, or unlit. If lit, it is about to reward the player something cool. If unlit, it doesn't give anything. Maybe this can be used to do something like:
1. if unlit, it shows the eye (evil mode), or shows nothing until the switch is hit, THEN shows the eye
2. if lit, it shows selected scenes from the movies.
Of course this would need to be wired into the game to get triggers when the switch is hit, and when the palantir was lit to work.
Can that be done?
