Many years ago when the original Linux Journal was still a thing, they ran an annual Obfuscated Perl contest which was, arguably, the best thing in the magazine. In one issue someone created a Perl program to play the game of Go against the computer and they formatted the code to look like a Go board with the starting black and white pieces placed in their starting locations. I have been unable to find that anywhere...apparently my google-fu is just sna-fu. Do any (older) readers happen to have a copy of that or know where I can find it?
