my wife's out of town for a few days. we're doing some redecorating, which (of course) I've been put in charge of implementing; but I ran into some issues with the proposed changes (i.e., they weren't possible). knowing that a simple explanation wouldn't do, I was able to *show* her using FaceTime. very cool.
it was also neat, of course, to be able to talk to her "face-to-face" from a thousand miles away.
