Visual Psychophysics Studies

I use Random.org to generate a random order for multiple stimuli used in human psychophysical testing. It's a welcome improvement over the book of random number tables I used in my youth, long ago.

Running Retirement Home Contests

Dr. Haahr, just a quick thank-you for your Random.org website. I run a weekly contest for elderly residents of retirement homes in the US, and I have to select a prize winner from all the people who submit correct answers. So every week I assign sequential numbers to all the correct entries, and use your website to select the winner! Just thought you'd like to know your website is a valuable resource for us. Thanks again.

—Jeff Pepper, Touchtown, Inc., USA
