I do a lot of Mac/iOS UI development and use ImageMagick to make before and after GIFs from screenshots. It's incredibly useful. This is my one-line makegif bash script that I use by dragging images from the desktop to Terminal after the command:

convert -delay 80 -loop 0 +dither "$1" "$2" ~/Desktop/"`date +"%b %d, %Y, %H.%M.%S %p"`.gif"
