OS X's iTerm2 terminal emulator supports inline images. Obviously, there has to be a Giphy command line client to properly take advantage of this:
giphycat requires either Python 2.7 or Python 3.5+ (and possibly earlier versions of Python 3, although they haven't been tested). Use pip to install it:
$ pip install giphycat
When run with no arguments, giphycat fetches a random image from Giphy and displays it in the terminal:
$ giphycat
Any other arguments are treated as a search phrase, and giphycat will return one of the images for that phrase at random:
$ giphycat boston terrier
$ giphycat creqcrqwrceqwrceqwrq
Unable to find any GIFs for 'creqcrqwrceqwrceqwrq'
