Rotating Control Panels
A Rotating Control Panel is a set of control panels that rotate either vertically or horizontally and then lock into place for play. Classic examples include 1UP's Rotating Control Panel and Frostillicus Arcade which features three control panels that rotate vertically such that two of the panels are always hidden within the cabinet. Another variation is Rototron where only a portion of the control panel rotates.
The main advantage of a rotating control design is that it allows you to include two or more individually designed control layouts without sacrificing artwork or playability. The disadvantage is the added cost of duplicate controls and complexity of designing the rotating mechanism, panels and routing the wires.
