Interesting story tonight - and looking forward to it.
In a similar vein, others might also like to read an arvix paper by Ray Norris and D. Hamacher "

http://arxiv.org/abs/0906.0155 This has some perspective from the ancient peoples of Australia, away from the slightly more

Regardless, it is a nice primer and an interesting and thoughtful article on its own!
