Speicus is a character and/or object in Zelazny’s Doorways in the Sand, an organic computer designed to integrate with a person and augment their perception and intuitive analytical abilities in the interest of collecting sociopolitical data.
“Speicus” is also the name assigned to Nick’s 12” iBook, with which he has developed a bizarre cyborg-like relationship, and which vastly enhances his ability to annoy others, especially at a distance.
