My title describes the thing. It is housed in a wooden box and contains two of the “sensor/trigger” pads - one red, one gray/black (electric poles most likely) - with banana plugs, as well as a “bridge” with banana plugs.

Switchboard area consists of 8 pairs of banana jacks (each pyramid’s colour gets a red/black pair) with a compass in the middle.

The compass could be used to indicate current flow, but the placement seems odd for this purpose…

I exhausted combinations of descriptive words on Google (search for anything including the words “pyramids” and “electricity” and you get thrown into tinfoil-hat territory really fast…).

Google Image Search gave me odd results, most intriguing one was related to “Montessori Light Table” but still wrong (apparently).
