Quoting 2H4 (Reply 7): Well, we may as well make this thread into a game, eh?
Clearly it is a pigeon denial device (PDD). Everyone knows that bird droppings are murder on paint. When the aircraft is going to be parked for an extended period of time, the crew must remember to deploy these to keep the birds from landing on top of the fuselage. The slight increase in weight an complexity is made up for by the reduced cost in cleaning and painting. Boeing will include them as standard equipment on the 787. Airbus is scrambling to include them in the A380. And that is the real reason for the production delays. You can fit a lot of birds on top of one of those Airbuses.

Quoting GAIsweetGAI (Reply 12): No, unfortunately I don't know enough (or anything actually) about this system to tell what A/C that is.
That's a good sign, actually. It indicates your mind functions normally, and that you have something that resembles a life outside of aircraft photos and basement aircraft knowledge.....unlike some....uh....people I know.

Then I will go with some sort of spoiler. Flight or ground I can't say. Only problem is I am not sure if I am looking at a leading or trailing edge. Lack of visible control surface leads me to believe leading edge. Lack of ice protection makes me think trailing. Of course I am assuming the wing is intact here. How about a Casa 212?

Quoting 2H4 (Reply 10): Quoting GAIsweetGAI (Reply 8):
Would that be some kind of spoilers?
Yep! Can you identify the airplane?
These are spoilers? How are they extended/retracted? My first guess would be cable system, although it would be pretty cool to see hydraulic mini-actuators.
In your picture, it looks like the trailing edge of a wing in the foreground, and the tapered rear fuselage in the background (with lots of rivets). It reminds me of the planes that were built back in the golden days, when we as engineers, pilots, etc, still were trying to figure out how aerodynamics worked.
