Trying to answer the question in http://stackoverflow.com/questions/12233105/how-can-i-display-an-image-in-the-terminal/22537549?noredirect=1#comment41404352_22537549 :

Is there any sort of utility I can use to convert an image to ASCII and then print it in my terminal? I looked for one but couldn't seem to find any.

I thought that the Ipython notebook is pretty good at doing it. You have to prepend bash commands with a bang:
