Warning -- Do not attempt to read the entirety of the original text of the Time Cube web site even if you can find an archive of it. If you think you've ever seen a "wall of text," whatever you're thinking of pales in comparison to the monumental screed that Gene Ray put together and slapped on the internet. It's a completely incomprehensible monolith of run-on sentences and whackdoodle ranting in eye searing colors peppered with random bolding and underlining. You can glance at it to get the idea, but trying to process the entire thing will probably leave you just as insane as the author by the time you get to the bottom.
