Now, I know that the title sounds a little soft, but my purpose is that everyone knows about a ninja. They move silently and stealthily, poping out at the right moment.
My question here is that, does anyone know about "ninja" techniques, silence while moveing, and stealth, the works? Clothing to blend in, human eye patterns, stuff like that?
