Your project is wonderful; thank you for making it free and flexible for public use. I use it every day in my 7th grade classroom to assign warm-up problems to students in my class; this particular crop of kids is highly competitive and I was having trouble selecting from a group with all their hands up!

I read your FAQ and I wanted to contribute a little thought: to a computer, would it think it has free will? We store and process information in the same way; so we are running a big program which makes decisions based upon lots and lots of current states and simultaneous inputs. I suspect it is impossible to know whether we have free will from within ourselves and will have to use lots of expensive computer modeling to answer the question, but I'm guessing the answer is no.

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.
