Need to gear up for the fourth? This cool little fireworks screensaver should do the trick. We're usually pretty boring when it comes to screensavers, sticking to the standard pre-installs. But this one wowed us with its realistic sound effects and graphics. They've pretty much the encapsulated the firework experience. There are bunch of settings to play with, but to be honest we didn't try them out. The standard settings alone were fairly impressive, as you can see for yourself below.
