I am seeing this thread only after about 30 replies are posted.
This has got to be the WEIRDEST thread I've seen in 25 years on the net.
I know a troll when I see one.
No! The OP is NOT the troll!
REPEAT: ---> OP MaxwellShih and associate raacampbell ARE NOT TROLLS!!!!!
However, he is -being- trolled, in a sense. More accurately, this is some sort of arcane psychological -experiment-.
OP has been tasked with solving a problem which he has absolutely no experience in. That's odd. That's not right, so I think the true answer is deeper than that. Further, OP was given a spec, and was advised that he could get some good advice here.
-I- think this -forum- is actually the target of the experiment, and MaxwellShih is an unknowing and unwitting participant.
The -experiment- is whether with near-zero information the forum can -devise- some sort of test for these alleged fruit flies using alleged LEDs and such.
The reason I say alleged is that the flies and LEDs are yet another -level- of this complex smoke screen!!! The mysterious force behind the experiment could have named 'Canada Geese and sunflower seeds,' or pretty much anything else because only the -journey- matters not the -destination-.
The Q is, forum, do you -understand- The Force? Can you -see- The Force? Or, to paraphrase Bill Murray, can you BE The Force?
I think I've been watching too much Person of Interest.
