A solved Ghost Cube. It’s almost, but not quite, entirely unlike a Rubik’s cube: it’s all white, the pieces are irregular 3- to 6-sided polygons, and the lines between the pieces are not continuous, making it look like the faces cannot rotate.

@VoltPaperScissors Now I’m thinking for the connection between rotors, maybe a strip of metal a few millimetres wide, bent on one side and taped on the other, so it’s springy.

Side view of the top of two rotors. There are two orange lines that represent the conductive tape of each rotor, and a line that represents the metal strip. It starts from the left side of the conductive tape on the right rotor, and goes to the left, a bit up, until it’s above the conductive tape of the left rotor. There, it’s bent down and back up, making it shaped like a square root sign that would have tipped to the right due to its weight.

The home theatre receiver is in the bottom left of the centre, the 5.1 speakers connected above it. Below are a mixer with three mics for karaoke, a Blu-Ray player and an Xbox 360 with Kinect. Above is the TV (via HDMI ARC), FireTV Stick and MiSTer with two arcade controllers. On the right are the router, network switch, fibre plug, and fibre transceiver to the office. The TV, MiSTer, receiver, Blu-Ray, and Xbox are connected to the switch via Ethernet. Each device also has its power source represented and labelled, whether a 230V mains wire or a DC power adapter.
