Follow a night full of fireworks filling the sky with a day of fireworks filling your WinMo screen.
Astraware (the geniuses who brought us Bejeweled) unleashed a free Fireworks app for the July 4 holiday, and you can still snag it if you want.
OK, it's not quite the same as sending miniature ICBMs into the sky. But it's free. And you're far less likely to blow off your hand.
