It's an updated DOS. If it works and its what you want, who cares why it exists or who made it?
The core features are like that of an updated DOS, but the extraneous features are much more interesting. The included games, for example. The hymn maker is particularly unnerving. A lot of his programs utilize random sentence generation, which he believes to be a medium through which God can communicate. I've always been curious about the literary and visual expressions of radically deviant minds, but I'd never thought to seek out software born from insanity. Wouldn't you like to read a novel about a deity who lives in an obscure operating system, built and maintained by a lonely schizophrenic?
