# The Ruby Blocky Image Viewer

**tl;dr: terminal image displayer that’s a shameless re-write of [icat](https://github.com/atextor/icat) for Ruby**

![tldr](https://raw.githubusercontent.com/bogwonch/ruby-blocky-image-viewer/master/images/tldr.png)

## Summary

So you want to see an image, but don’t wanna leave your precious command-line?

`jp2a` makes you sad...
