Don't know if it's what you're after, but at around 23:30 in the 40 minute interview, they do a real-time demo, with the interviewer moving around in the world.

I watched the 40 minute thing where they move around and it is interesting. Static objects look amazing, and that little laptop they were running it on has promise that with better processing power, maybe animation would be possible. I am withholding wrong opinion until they show animation. Granted, I haven't put out any sort of investment towards this, so no loss on my part.

For less then 5 minutes before the guy almost ripped the laptop out of his hands.
