The apparatus may include a system for controlling deployed fixtures. The system may receive user commands different devices in different formats. The fixtures may be independently addressable. The fixtures may be magnetically supported by a fixture support. A brace may join two or more fixture supports without reducing space available to support fixtures. The brace may join a fixture support to a fixture support accessory. An accessory may include a variable-angle junction. The fixture may include articulating joints for controlling the direction of a beam. The fixture may include a lens having an electrically controllable beam spread angle. The fixture may be stowable in the fixture support. The fixture may be slidable along a cord to adjust a height of the fixture. The fixture may include an extendable ring. The system may coordinate motions of the fixtures to follow a target. The fixture may include an elongated board. The elongated board may include a non-polar power socket. ## Claims ### Claim 1 An apparatus comprising: a junction that: defines a central axis that defines continuous angles about the central axis; and defines a circumferential housing having an annular recess and configured to: removably receive, in the annular recess, a first fixture support bracket and a second fixture support bracket; and secure the first fixture support bracket at any of the continuous angles and the second fixture support bracket at any of the continuous angles which are not obstructed by the first fixture support bracket; and a peg configured to: extend into the annular recess; and prevent removal of a fixture support bracket from the junction. ### Claim 2 (depends on 1) The apparatus of claim 1 wherein the junction is further configured to provide electrical communication with the first and second fixture support brackets at any of the continuous angles. ### Claim 3 (depends on 2) The apparatus of claim 2 Wherein the junction includes: a track configured to slidingly support the first and second fixture support brackets;
