Because Engineers’ Puns Never Change

bytegeist (n.): Originally a trademark of Epiphani, ICC, the term bytegeist refers to a modular, multi-function, autokinetic accessory for one’s¬†muse (q.v.), providing physical-world interface, scanning, and manipulatory ability independent of those of the muse’s host.

(As was inevitable, earlier single-function muse accessories were immediately rechristened¬†bitgeists once the bytegeist reached the market; likewise, such accessories which work in conjunction with a modern bytegeist are naturally referred to as its “bits”.)
