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 wanted to knit a sweater and use yarn that I already had. In no single color was there enough yarn to finish the sweater. But I did have a type of yarn in equal amounts of 6 different colors, which when combined would be enough for the sweater. Blended together the colors looked great but I wanted the look to be random. Using numbers 1 through 6, your random number generator gave me a beautiful sequence for the colors. I also wanted the number of rows done in any one color to vary randomly from 1 to 3. A second list tells me how many rows to knit before changing colors.
