In several things that I do, I require some form of randomness (for example, secure primary keys for databases, with almost no chance of collision error). To do this, I use your site to create them. A simple generation of numbers between 0 and 35, and then change them into their base-36 equivalent, however long the sequence needs to be, and you have an virtually unguessable primary key sequence. You can’t guess what the next key in the sequence will be. Very useful for keeping people from being able to hack your customer list and finding out who does business with you (they might be able to guess one, but the next won’t be sequential, so they would have to start all over again to find the next). I also use it in my writing, to generate datasets for locations and people by assigning integers to various items and using the site to pick the ones that apply.

I am using your program to generate six random numbers between 6 and 9 to consult the I-Ching, the ancient Chinese book of Changes. The traditional method is to use yarrow stalks in a somewhat complicated procedure. More recently people have been using coins. It would be great if you could add a three-coin toss to your menu so that the I-Ching values could be determined. It would also be great if you could simulate the look of old Chinese coins. Just a suggestion, but thank you very much in any case.
