Notes:

Posted by @j4james in response to a person overly simplifying the process of implementing sixel graphics on modern computers. Sixel is a technology from the 1980s which allowed computer "terminals", which usually can only show text, to also display bitmap graphics. The image itself is a demonstration of how sixel graphics might work. What was especially clever about @j4james's post is that he subsequently posted sixel "source code" that does indeed draw the image from the meme on a Digital VT340 terminal.
