Then you start to see the shift into the future: Personal flying cars, Hypersonic jets, and now...what is essentially an Audio Laser that can project sounds into your head (note the obvious mistake in the illustration: These speakers would have to be ceiling mounted to avoid disruption from objects and people walking in front of them. But I digress...).
However cool this is, I'm not posting so much because of that, but because of Roni's rather intriguing response to the technology when I told her about it. "You know...this could be handy in a BDSM context. You restrain someone, blindfold them...and then can put them into almost any sound environment".
That's twice in as many days she's surprised me like that. I'm starting to wonder if something is rubbing off on her.
