James, or is that Capt Kirk? :),

As a quick first pass, I'd think you could use a regular RC=20
transmitter/receiver for the wireless part.  Use something like this for=20
the transmitter... http://www.reseau.org/arduinorc/ , or interface to=20
the transmitter like this...=20
http://forum.arduino.cc/index.php?topic=3D8755.0 .  Then you need to=20
interface the head tracker into that arduino.

On the receiver end, you can use the standard receiver to standard=20
servos for pan/tilt, and then use a receiver-controlled switch=20
(something like this...=20
http://www.hobbyking.com/hobbyking/store/__46040__Turnigy_Receiver_Controll=
ed_Switch.html=20
) for the lighted eyes.

Alternatively, you could use something like an RFduino for the wireless=20
part, and that one "channel" would carry all the data as you encode it. =20
But that's more involved.

Cheers,
-Neil.
