I confess to being a big fan of the flappy information displays we used to have in our railway and airport terminii, prior to the introduction of plasma screens, which more or less force you to stare at them constantly, lest you miss an update of the information.
At least with the flappy displays you'd have an audible alert (by way of a satisfying sound) to let you know that the information was being updated.
It would have been easy to make the plasma screen ding, bong or otherwise alert the traveler of an update.
They missed a trick there.
Hell, they could even make the plasma screen make a tiki-taki sound if they'd wanted to.
They could've also kept the flappy display look, and had it displayed on the plasma screen.
I despair.
Sometimes.

ETA - Interestingly enough, as far as I'm aware Vienna airport is one of the last places to have used the Solari (for that is what they are called- named after the Italian company which manufactured them) display boards.
But, in a reassuring twist, Quantas have re-introduced them in their departure lounges.
To paraphrase Quantas 'On the basis that they are art'.
Love it.
