Some of you may remember this absolute diamond of insanity that was the "4-Day Time Cube." This was the go-to example of the internet as a universal amplifier for communication - for both the sane and insane alilke. It was there from nearly the start of the world-wide web, back in the 1990's. Alas, it ceased to be some time ago, but it still lives on in our hearts.
For the uninitiated: welcome. Read and join the rest of us that are "educated stupid."
