ICBM stands for "Internal Cinema Beautification Module".

It's a surgical implant that digitally "paints" your retina, making your tiny cable strewn sub-basement theater with the half-broken couch you salvaged from a frat-house fire sale look like a $200K custom installation with motorized drapes, plush velvet movie-loungers (leather available with minor device tweaks) and a beautiful usher to show you to your seat.

Gotta get me one of those!
