The Hall of Useless Gadgets

From HallsWiki

Sometimes new gadgets are created that really aren't useful. Or aren't as useful as their creators think they are. Or are rendered obsolete by something much cheaper that is already in existence. When these devices are discovered by a Hallsian, they are showcased in the Hall of Useless Gadgets in the Teraflophouse.
