Rounds provides fun and intimate video chat via Facebook
With that said, I don't much care for the interface -- it really feels quite cramped inside Facebook's mega-narrow center column -- but it's easy enough to use with a bit of trial and error. Almost the entire UI changes as you mouse-over things, which is probably quite handy after you get used to it, but it's confusing at first.
Back to the topic of friendliness: I have to admit, I was pretty dubious at first. Rounds is a Flash app, and my only prior experience with Flash-based video chat was a brief stint as an anonymous phallus on Chatroulette. But I needn't have worried; the entire service seems to be about bringing people closer together, but without the massive spam of dribbly man bits.
And that's the key to Rounds: you're encouraged to mess around. You can mess with your own face, or you can mess with your friend's -- either way, you'll both see each other's reactions in real time. In the photo above, Natasha had no idea that I was about to beatify her with a halo -- and the glowing grin that I received positively filled my heart with joy!
I've only touched on the video chat aspect of Rounds, but there's a lot more. Like MSN Live Messenger, there are games like Checkers and Backgammon -- or even Spin the Bottle (with built-in questions and dares!). One of the coolest features is the ability to 'share' a website; you can open up Facebook or Flickr and share the mouse, navigating this way and that. (What a great way to share a photo album with friends and family online!) There are also some FarmVille/Facebook'ish aspects like Coins and Gifts, but I haven't played with them yet.
In conclusion, Rounds converted me from mature-and-serious into a wobbly pile of giggles. That's not bad for a Flash app and a five minute conversation.
