This demo page
http://www.whatwg.org/demos/workers/primes/page.html
from the Web Hypertext Application Technology Working Group shows prime numbers. What I found interesting is that initially, it takes a few moments to find prime numbers; meaning that they are "far apart" as you examine every number up to say 1,000,000. But suddenly the demo application is spitting out prime numbers faster than you can read. So, apparently there are a lot of prime numbers once you get into the larger numbers. But this isn't actually true. If you [http://yoyo.cc.monash.edu.au/~bunyip/primes/ look at the distribution of primes], there are "more" smaller primes than larger primes(X < 200) <ref>http://primes.utm.edu/howmany.shtml</ref>. Hmm.

With "workers" you can perform a computationally expensive task without interrupting the user interface.
In this example, the main document spawns a worker to (naively) compute prime numbers, and progressively displays the most recently found prime number. == Word of the Day ==pul-chri-tu-di-nous; adj.
