A slightly unobfuscated version of that code:

  counter=0;
  pointer;
  main(){
    while(counter<641){
      for(pointer=0;
          "##K#8(38D-##C]L5870.X7\\M_b;90\\"
          "MC-M/NZGB6Q,I0VGB6a0FbN<VG.6Q\\bNb7^@`X=N@`XQaOVX:^]NX=:Z8PY]B`:>P"
          "NY8^$#SM):XA"[counter/6]-35>>counter++%6&1;
        pointer++);
      putchar(" _/\\\n,`)('<-"[pointer]);
    }
  }
