OVERLOAD- the lag machine that lasts.
That's a huge number.
And it doesn't take a computer to count down from 9 quadrillion 100ms, so what it does, is it repeats the countdown, adding a "generation" every 100ms. This means that it wouldn't only take DECADES to stop, but it never ends! If it does end, and i=0, it says "HAPPY NEW YEAR".
Also, you could just paste this in the average browser console, and lag out anything, really.
Mostly, have fun.
