Temporary Injectible Eye Coloring

From HallsWiki

The eventual winner of the Battle of the Ideas Doomed to Deferred Success, Temporary Injectible Eye Coloring was an idea conceived by Slovman as a way to dye one's eyes a different color by sticking them with a needle. Perhaps needless to say, its victory in the Battle was largely due to the Hallsians responding with a collective shudder at the thought.
