The Super Twister is a console made by Fun Dimension Inc.. It looks like the top screen of a DS, but when you twist it, you can cause things to happen in the game. For some games, you can get a bottom part that can connect in order to use buttons (A, B, X, Y, Control Pad) if required, but only a couple.
There are two handles at the bottom of the system, which you can hold to twist it. It also has Wi-Fi, similarly to the DS.
