Very cool indeed. In the comments was a link to an XKCD cartoon. Its tool tip mentioned "twin primes". Looked that up. Google pointed (of course) at Wikipedia. Read that. Backed up to the Google Search, and noticed there is a news item from 15 hours ago that an unknown mathematician at the University of New Hampshire has proven the twin primes conjecture: http://www.wired.com/wiredscience/2013/05/twin-primes/
This is nothing to do with the original post. It's just amazing to me how short the distance between one very interesting topic on the net and something almost unrelated can be. Skip -- http://mail.python.org/mailman/listinfo/python-list
