Claim 14:
15. A device comprising:
a first platform having a first side;
a second platform having a second side positioned to overlap the first side of the first platform;
an actuator that rotates the first platform relative to the second platform and about an axis of rotation of the first platform;
a first coil included in the first platform, the first coil comprising a first plurality of conductive loops in a first coplanar arrangement substantially parallel to the first side;
a second coil included in the second platform, the second coil comprising a second plurality of conductive loops in a second coplanar arrangement substantially parallel to the second side; and
a plurality of light sources included in at least one of the first platform or the second platform, for emitting light toward the other of the first platform or the second platform,
wherein at least one of the first plurality of conductive loops of the first coil or the second plurality of conductive loops of the second coil are patterned on a printed circuit board (PCB) and concentrically arranged about the axis of rotation.
