As you know, computers can't actually generate random numbers. So what do you do if you need hundreds of random numbers per second?

In all, it takes about 13 seconds for an individual die to make a round trip. There are 200 dice in the machine, each rolling four times a minute, totaling over 1,330,000 rolls a day.

The dice are "Michigan Red Eyes", which have different colored pips for each value. The different colors make it pretty easy to count rolls. For example, if 6 yellow dots are found in the image, there were three 2s rolled, no need to worry about determining the proper grouping or orientation of pips.

Of course, I would have done the ADC + static noise method, but still this is pretty neat . . .

Casinos to generate random numbers. Guys at MIT have cracked electronic random number generators to predict what the next number would be.

Yep computers use the current time to calculate "random" numbers.

Random does not exist, ever.
