Tom Murphy presents a humorous yet functional computer architecture built entirely on IEEE-754 floating-point NaN and infinity values.
A new kind of computer architecture that's more elegant than 1s and 0s, being based directly on Mathematics. Note: Everything in here is real (IEEE-754), but the target is computer scientists and the troll level is set to ULTRA. Source code and stuff: tom7.org/nand/Why it's here
