INVISIBILITY SOON ? Meta-materials ? Quantum stealth?

Invisibility has been one of the finest ingredients for wide range of novels and films, from Star trek to Harry potter, from the Invisible man to Lord of the rings and so on. How can one ‘cloak’ or ‘obscure’ an object or even people from an observer’s field of sight? Trying to make invisibility a real phenomenon rather than a myth would have been just hilarious if tried in the early eras of classical physics (Newtonian physics) dominance.
