The Gentlemanly Escort Cube by *Risachantag
From the description:
The patented Gentlemanly Escort Cube is a must for all unchaperoned Victorian ladies finding themselves in indelicate situations that might upset their fragile constitutions.
The Cube excels particularly in warding off the untoward advances of stray turrets and politely holding down buttons for her as she proceeds along her way.
The Aperture Institute of Natural Philosophy reminds you that the Cube does not initiate conversation, and certainly not if you have not yet been formally introduced.
