eye candy: /i:' kand`ee/ n. [from mainstream slang "ear candy"]
A display of some sort that's presented to lusers to keep them
distracted while the program performs necessary background tasks.
"Give 'em some eye candy while the back-end slurps that BLOB
into core." Reported as mainstream usage among players of
graphics-heavy computer games. We're also told this term is
mainstream slang for soft pornography, but that sense does not
appear to be live among hackers.
