一个碎片屏保

效果没有理想中的好。
纯粹利用 as 实现，这样一来，因为全部由CPU计算，使得 CPU 使用率巨高，甚至高达 100％（偶的 CPU 是 AMD Athlon 2500＋）

fscommand("fullscreen", true);
function createmc(i) {
	x = Math.random()*1024;
	y = Math.random()*768;

	x3 = Math.random()*40;
	x4 = Math.random()*40;
	y1 = Math.random()*40;
	y2 = Math.random()*40;
	y3 = Math.random()*40;
	y4 = Math.random()*40;
	color = Math.random()*0xFFFFFF;
	alpha = Math.random()*100;
	_root.createEmptyMovieClip("fd_mc"+i, i+10);
