Signer Cube (3.5e Equipment)

Signer Cube
These illustrious cubes are the invention of an Aperture Magic alumnus by the name of Motskalla Sarcus. A signer cube consists of six luminescent panels lined with ribs of finely engraved orichalcum. Contained within sunken flats on each of the cube's six faces lie buttons that, when pressed, make the corresponding face light up in a particular color. Each of a signer cube's faces can assume the primary colors red, yellow and blue, as well as the secondary colors orange, green and purple. The true purpose of these cubes however belies their somewhat fanciful design.

Signer cubes are meant as a form of communication in code. Utilizing Motskalla's newly proven theorems on quantum entanglement, one or more signer cubes can be linked together so that when the state of one of the cubes is altered, the other cubes change to match the new state; when the color of a particular face is changed, the same change also occurs on the other cubes. As such, with 6 sides that can toggle between 7 distinct settings with a press of a button (red, yellow, blue, orange, green, purple or 'black'/inactive), signer cubes can transmit a maximum of 76 = 117,649 different states of information between themselves, across any distance. The entanglement effect is maintained regardless of distance between any two entangled signer cubes, and any change of state is transmitted instantly without spatial or relativistic time lag, regardless of whatever physical or magical obstacles are between any two cubes. Signer cubes even work across different planes.

Signer cubes become quantum entangled during their creation process. As such, any signer cubes intended to work together must be made together at the same time and in the same place, in batch. Once a signer cube is quantum entangled to a distinct array of other cubes, it remains entangled to those other cubes indefinitely, until either disjoined or completely destroyed. The entangled state of a signer cube remains even in an antimatic field.

A signer cube is approximately 3 by 3 by 3 inches and weighs 2 pounds.
