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.
