Pounce is a kickass way to show GIFs in the Terminal. Here's what you need to do:
Install Pounce with:
npm install pounce
Pounce currently only has one command:
show, and it accepts three parameters:
file.gif is the file path to the GIF file,
scale is a value from 0 to 1, where 1 is the image's actual size, and
frame_interval is how long each frame is displayed.
So to throw it all together...
var pounce = ;pounce;
Here's a quick preview of what that code outputs. It's a bit glitchy because my Mac hates me.
