While you're reading this text, your browser is finding prime numbers. You probably figured that out by the little indicator above, but I easily could have hidden it. In fact, I could install this on every site you visit, and you'd hardly notice. The point of this project isn't to find prime numbers. If it were, I'd be using a real prime-checking algorithm and only check Mersenne Primes. The cool thing is that I could be solving a real problem, and someone or some company could be paying me for all the work that people's computers are doing when they visit my site. I'd much rather donate CPU processes to advertisers than donate screenspace to their ads.
