I've been having some issues with my design, I hope BlindVoyuer is doing better.
The issue is tied to the fact that with the distance a player stands from the Palantir on the playfield, the video image source behind it needs to be several inches behind the Palantir to be visible. If the image is too close to the crystal it warps completely out of focus into a blurr. The crux of the problem I'm having is that there is some critical stuff several inches behind the Palantir on LOTR that can't be moved. If I try to raise the video screen high enough to be out of the way, it becomes visible only to someone standing with their head a few inches above the lockdown bar. So my prototype is all set for those of us with toddlers or midgets in the family that like to play pinball, but everyone else can't see squat
I haven't seen a WOZ in person, but I'm assuming this isn't a problem on it because they were able to design plenty of space behind that ball.
The good news, is that I do have a projected static image of the eye of sauron working behind my ball. It becomes visible to anyone in the typical playing position, and lights up and entire crystal, making it glow red, when the Palantir is lit. It looks cool - but definitely not as cool as a video of swirling smoke that slowly changes into the eye of suaron when the Palantir is active.
