[from the movie "Star Wars"]
1. The AT&T corporate
logo, which appears on computers sold by AT&T and bears an uncanny
resemblance to the 'Death Star' in the movie. This usage is
particularly common among partisans of BSD UNIX, who tend to
regard the AT&T versions as inferior and AT&T as a bad guy. Copies
still circulate of a poster printed by Mt. Xinu showing a starscape
with a space fighter labeled 4.2 BSD streaking away from a broken
AT&T logo wreathed in flames.
2. AT&T's internal magazine,
'Focus', uses 'death star' for an incorrectly done AT&T logo
in which the inner circle in the top left is dark instead of light
-- a frequent result of dark-on-light logo images.
