After brunch, in front of Cupcake Royale.

Once you have the frame images in gif format (say, 55.gif, 56.gif, 57.gif and 58.gif), you can use imagemagick to make them into an animated gif with 50/100 seconds interframe delay like this:

>convert -delay 50 55.gif 56.gif 57.gif 58.gif -loop 0 animated.gif
