As you've provided no explanation of what it is you're linking to, that's kinda hard to determine.
The better post would have been :
"Here's a video from MS Israeli RnD showing Natal's sensing."
Don't worry about posting stuff that's been posted before. That's far less annoying than random links!
On topic - Good video! The time to recognise the fella was very quick, and lag was pretty minimal. There was only one oddity towards the end as the data points changed colour from vibrant to very faded, as if it suddenly lost depth resolution or something. There was also a strange bit of noise on the girl's detection, with hot spots on her left hand. I think that's a ring and bracelet, with a buckle showing up on the waist, suggesting reflective materials are affecting the depth perception somehow. Curious...
