I want to control movement of way lighter objects (was thinking about 1 LED inside plastic). So I figure that I can use small servo to accomplish it. But, a question spring to mind, how can I make the servo control the length of wire like in that video? Is there any mechanical diagram that I can follow? Especially regarding how I can build appropriate servo leg for such purpose..
Maybe something like this, a small variation on the big tape drives.
Magnet wire? 30 guage wire wrap wire? Don't want the insulation distracting from the show, maybe black colored wire.

Doubt it, those baubles are shiny, not lit from inside. The "wires" are probably fishing line,
there will just be a little drum for each "pixel" driven by a stepper motor or a servo motor/
encoder setup.
Wow thanks for the ideas guys. I have to agree that this might be a stepper motor and a reel and it's easier to imagine since the objects are moving downward relative to the motor.
Now, what if the motor is in the bottom and the objects should move upward first? Should there be any supporting force or leg that does the trick?
the drops on the airport sculpture appear at the end of the video to be at the end of the wire.
this like shows a similar Kinetic Sculpture with the drops on the ends of the wire.
for the wood box, I would use a threaded rod and a motor. the box looks like it is 20x20, so there would be a lot of motors if every stick was controlled individually.
I would offer the drops on the Sculpture are run from steppers, not servos.
the semacode sculpture could be simple DC motors that reset to zero by retracting to the stalled position. small CD motors could easily fit in the wood. the ones on my quadcopter are very tiny.

Hmm, this looks like an interesting solution. What do you mean by simple DC motors that goes to stalled position? Perhaps a motor with added objects so that it can move the wood back and forth? I'm just curious how can I make motor that does such thing?
CrossRoads:
The wood sticks are nothing like LEDs on a wire. Which are you really after?
I think I've been pretty bad here, terribly sorry for the mixed up. Maybe I should edit the thread title.
I just want to know how can I make servo move thing up and down. What I had in mind is similar to those sticks, only I want it to move up and down.
But linear actuator seems pretty overpowered. Perhaps I can use combination of motor and strings? Or pulley? I'm just looking how to make the proper motor/servo leg for my need.
