Bandersnatch Opticals, stylized as bandersnatch opticals, is a brand seen during the saving and loading screens of American McGee's Alice. It can be read at the very top of the loading screen in very small lettering, implying that they created the machine the loading screen runs on. Due to their name, they are simply a company that specialized in optics.
The company's only known product is a large machine with several screens and buttons. It is made from wood and has titles engraved into some form of unknown metal. Due to the time period and company speciality, it could be possible the machine is some form of Graphoscope, wooden Camera Lucida, or some other form of viewing equipment (or is based on one of these).
