Hyper Random Image

Change background-image on every activation of Hyper.js

How to Use

``bash
$ mkdir ~/.hyper_images
$ hyper i hyper-random-image
`
Next, you put images (.jpg, .png, .gif) into this directory,
then terminal chooses background-image from them randomly.
Try ⇧⌘R (Super-Reload)!

This plugin uses decorateConfig Event on Hyper.js, so it changes background-image randomly when decorateConfig Event Triggered (on Super-Reloaded, or on save ~/.hyper.js` etc.).
