I'm as guilty as the next person. Perhaps more so. I was caught up in the "Cool sites"wave a couple of years ago, and I even spread the message of those tools on many an occasion.

I can think of several that come to mind. For one, Xtranormal. You type out your script, choose your avatar(s), and make the move. The program makes the avatar read the script to you. Fun, probably. Cool, maybe. But, appropriate for senior...
