       | This is a pretty rad credential. ACiD and iCE were hugely
       | influential in my early career and I looked up to the early and
       | late members. Very cool.

       | things like the spades, diamonds and hearts I see on the page)
       | 
       | > So then we can loop over every permutation of background color,
       | foreground color, and character and compare it to the image's
       | character and pick the one that has the lowest number of
       | mismatched pixels - ideally 0.
       | 
       | This is also the technique used in derasterize, even if we wanted
       | to try funnier things, like a Hough transform to spots the
       | circles (application: a bloom-filter like approach to try the
       | things like deg o O just right where they are needed) or a FFT to
       | isolate zones by grainyness and apply different criterias for a
       | more perceptive approach (application: the Sixel lemur example
       | has fine hair, very thin in pixels but important to keep if the
       | pixels create a line of high intensity given the background
       | color)
