great youtube clip, kame
I'm not a programmer or engineer ... so maybe my comments will sound naive
At first glance, I presumed that there is a digital program controlling the flow of ACTUAL water drops -- opening /closing "micro-gates" -- so that each row has a unique distribution of water
BUT given the appearance of downward curving water flow, I started to think that the display uses a large and very thin, transparent LED screen -- on which is produced the ILLUSION of falling water
which is it ???
in any event, it's beautiful ... domo
attends, attends, attends ... another thought ---->
is there actually water flowing inside the thin LED screen -- continually splashing and evaporating at pixel locations, in the same manner that LIGHT and COLOR is distributed on a computer screen ????

In fact, your first explaination is the correct one, it's a hundred of small electrovalves reproducing a bits line. The best way to envision it is to imagine an unrolling paper roll, and a hundred of big pens with two possible states: up or down. Another way to see it is as a thermal fax machine, same principle applies :)
Your latest idea is very appealing, but I don't want to think about the cost in setting such a machine up :-)

aha !! you passed the test ... your English is perfect
(and if you can talk as well about FRIED CHICKEN and the NBA,
you'll get through Immigration at JFK in a flash !!)
Can state-of-the art technology produce a TRANSPARENT screen that reveals no hardware ( I suppose that is essentially a hologrammatic field)
artistically, in the clip, I loved watching how they've ingeniously designed MOVING DARK SPACES in between the water flow
I know you write computer programs (and reconfigure watch circuitry) -- how much training do you have on the hardware engineering end ?

Ha non, je ne peux pas parler du Colonel Sanders, je suis disqualifié d'office :)
Otherwise, for the transparent screen it's already doable, but you will always need some sort of framing, even if it's not on all four sides.
For the hardware engineering part, no training beyond school!

it's a lot of fun to hear your English voice
you sound entirely natural, very casual, like an old American friend
(at Immigration the important thing is to act relaxed -- like you've never once in your life heard of GUANTANAMO -- and you gotta chat up the INS agent about something in USA pop culture that makes you seem like the boy next door)
(( don't let Heidi talk about DEXTER ... yes, I know that's pop culture, however ....))
