Absolutely fantastic idea and execution. Props to the video producer(s) as well.
One question: what sort of power consumption is required to maintain the digit positions inside of the enclosure?

On the other hand, you are right, it only draws power when it moves and it moves every other segment every few seconds which is enough to constantly animate the numbers, because the fluid needs time to readjust.
The motors are actually stepper motors, which made it all harder, because its not as easy to move them as it is to move servos, and steppers have no idea where they are which required an initial calibration sequence. The good news is that steppers are not loosing any steps, i guess the mechanics work very well.
