Its not really comparable to a scoreboard. The biggest difference is that the light bulbs are fixed in place, and aren't being moved by gravity. You have to time exactly how long to let the water run, how fast to let the water come out, which faucet to release the water from and when. Its not as easy as it looks. Why do you think no one has ever done it before?
I'm not saying its super-mega-science on the level of the LHC or anything.
I'm just saying its much more difficult than you think it is.
If the good lord had intended us to go outside or have a social life, he wouldn't have invented the internet.
