Protagonists name

After a brief chat with Alex this morning, (which felt a bit like collaboration I have to say, so I'm quietly proud of myself), we have decided that the main characters name will be Ulam. We haven't decided whether its going to be his first name or his surname. Maybe I won't specify. I like Ulam because of its association with spirals and primes. 

You can even buy a t-shirt with the prime spiral on it. Its not on my Christmas list because, between you and me, sometimes I get a bit sick of primes.
