Love it. I wonder what the distribution of rolls/tosses for this looks like. This also reminds me of an automated dice roller thingy that someone built with a hopper of dice, a conveyor to bring the dice to the top of a ramp and ocr to record all of the rolls, a "Dice-o-matic" [0]. And a vidja of it in action [1].
