Fucking animations. You need them.
gifme is a simple command line tool to generate animated GIFs.
gem install gifme
You'll also need to install ImageMagick. On OS X, this is easy using Homebrew:
brew install imagemagick
gifme ~/Desktop/1.png ~/Desktop/2.png You now have a handsome animation at ~/Desktop/animated.gif
You can also glob, of course:
gifme ~/Desktop/*.jpg You now have a handsome animation at ~/Desktop/animated.gif
Super Advanced Usage
On some gifs, it's nice to have a smooth loop, so when it ends there's not a
jarring leap from the last frame to the first frame again. Use the
switch to create the animation like normal, and then reverse the frames and add
them to the animation so it looks like one smooth motion and back again.
gifme FILES --reverse
If you pass in a URL of a gif instead of FILES, we'll download that gif, split
it into its constituent frames, and let you recreate it. For example, you could
take a gif you find online and give it that
gifme http://tumblr.com/some-crazy.gif --reverse
You can also resize shit. We default to 500 pixels, but do whatever the fuck you want.
gifme http://tumblr.com/some-crazy.gif --width=1000
For other options, check out the help:
If you're curious, gifme was initially a few-line shell script in my dotfiles. Eventually it became clear that animation is a fundamental part of our society, and I split it out into its own tiny project.
If you're curious, I featured the older gifme version in a screencast I made that describes how animated gifs are an integral part of working at GitHub.
