to build this gif i just run one command (find all jpeg in starwars2 directory, resize to 312px wide, limit to 32 colors, then create an animated gif)

$ find starwars2 -name \*.jpeg | imgs2png.sh 312 32 312-32 | sort | imgs2gif.sh 312-32.gif
starwars2/10.jpeg (479980) -> 312-32/10.png (17560)
...
starwars2/29.jpeg (412894) -> 312-32/29.png (14936)
312-32.gif (665547)
