这个只能是单核CPU，多核心CPU做不到这个效果，主要用到了Sin Cos函数，和Sleep函数做出的效果。
上代码！
正弦波曲线
//正弦波曲线 double time = 0.0; double runtime; int c; while (1) { runtime = 100 + 100 * sin(time); time += 0.05; c = clock(); while (clock() - c < runtime); Sleep(200 - runtime); }
横线
//横线 while (1) { int start = clock(); while (clock() - start < 10); Sleep(10); }
单向斜线
//单向斜线 int k = -1; int c = 0; int runtime; while (1) { runtime = 100 + k * (c++ % 101); int start = clock(); while (clock() - start < runtime); Sleep(100 - runtime); }
双向斜线
//双向斜线 int k = 1; int c = 0; int runtime; while (1) { runtime = (int)(c < 100) * (100 + -1 * (c % 100)) + (int)(c > 100) * (c - 100); c = c++ % 200; int start = clock(); while (clock() - start < runtime); Sleep(100 - runtime); }
