Here is a video I made: https://www.youtube.com/watch?v=RURjQe0BAFQ

The video is a slow, soft-spoken reading of random numbers, courtesy of Random.org's integer generator. I was pleased to receive the following comment in response, from fellow YouTube creator ChillWhispers: “This is very relaxing. I enjoy the random order of the numbers, that way I don't ‘expect’ it to end. Your voice is very soothing.”

That was pretty much the effect I was hoping to achieve.

Thank you again for clarifying Random.org's terms and conditions for me. I was thrilled to be able to make this video.

Thanks for being awesome,

I study the life-cycle of viruses, and I perform lots of tissue culture experiments. In order to try to develop theories to explain some results I was getting, I wrote a computer program that uses a Monte Carlo scheme to simulate infection of cells by viruses. I need a different random number for each simulated virus, in order to randomly assign it to a cell that it ‘infects.’ In order for the results to be meaningful, I need to simulate tens of thousands of ‘cells’ and hundreds of thousands of ‘viruses,’ so I need hundreds of thousands of random numbers. The pseudo-random numbers produced by the Apple Macintosh built-in linear congruental generator proved themselves to be not good enough for the job, as I found that some numbers were chosen too often, a definite no-no for my purposes. Then I saw the NY Times article about this site and gave it a try. First I tried using Random.org numbers to seed the Macintosh generator at frequent intervals during the execution of the simulation, but it did not solve the problem. So I tested using all numbers from this site and they passed my quality test. So now I download several batches at a time of 10,000 numbers between 1 and 40,000 and string them into big files as the sources of my numbers. I'd like to be able to download them in even bigger batches, though. Thanks for a truly useful service!
