Hi Todd... thanks for that photo. The baby's even happier than you are. 
I don't like flash photography, but when I do screw it on, I use the Sto-fen Omnibounce. I am, however, always willing to consider something better. Unfortunately, I find Gary Fong's website and product descriptions to be unfathomable. Everything you click seems to take you to the video... "Ok, Jamie, come on in here..."
There's the Lightsphere with and without dome, I guess. And the Lightsphere PJ (Photo-Journalist). But I don't many details on the "with and without" and very little on the PJ. So I've never been able to decide with any confidence which I want, if any.
He also doesn't give any dimensions, so you've got no idea if you even want the hassle of carrying it around. Yes, it's vinyl, but there are stiff and pliable vinyls. Does the thing mash down or are you carrying a basketball around with you? Does the PJ version fold up? Since there's no top on the PJ, I assume that straight-on flash is just your normal flash (which isn't what you want), so you need to angle the flash at all time. Etc., etc.
Since he's not answering these questions to my satisfaction, he's not making any sales in Hong Kong. 
It was good to hear your experience, though. Now go clone out that single blade of grass due west of baby's ear. 
Cheers,
Don
