He replaces the hologram of the Woman with the superimposed monkey (or lemur, I forget which) eyes. The hologram looks pretty freaky, like a zombie or washed up goth rocker, and Palpatine looks like he took his meds this time. The only thing is his eyes are pretty yellow, while the rest of him is blue (like the hologram color). The Dialouge is altered, with the following lines (new parts in bold):
I am very glad that they did this, for I always thought the hologram looked like a fish in that scene.
