I forgot one
Vader Hologram - Poor quality, especially bad around edges. I don't know if this screengrab does justice to how bad this one looks on screen in motion.
The element is simply Vader standing, then putting his hands on his hips. You could paint the whole thing out and it shouldn't be too hard to find a simliar shot to convert to a hologram.
Riplin: The prequels had some bad acting, good design. The clone war sequence was the whole reason to watch AOTC. Adywan has already tied ANH more dirrectly into ROTS, so I'm just acting on that.
I'm just throwing out ideas. They're all just brainstorms. If Adywan uses one I can point at the screen and go "OOoooo!!!! OOoooo! Mine!!!"
