Those Geonosis shots are really amazing. I was just looking at those scenes and noticing the cartooniness as I got that sequence ready for youtube.
As for the above question about the night-to-day shot in Balance of the Force, its been there since the original version I did, I think.
Its the scene in where Jar Jar & the Jedi reach the lagoon and swim to Otoh Gunga. Its a night time scene in balance.
If you mean which scene with the lightsabers, there was infamous changing Dooku to being a fallen Jedi, so driven to destroy the Sith that he embraced the Dark Side to do it and making his lightsaber yellow/gold.
It was a sort of double homage. One, to Luke's action figure when I was a kid, which had a yellow saber, and to the original idea for Balance of the Force, when I was going to give Qui-Gon a yellow saber, did a few scenes and said to myself, "You know, he uses his saber an awful lot... F*#k it." and gave up out of sheer laziness.
Also, in Episode III since Palpatine loses his saber out the window, I explained that away by him obtaining someone else's saber shortly afterward, which is the one he uses against Yoda.
