From the schedule:
2:30 PM
Creating the Universe with Unity
Speakers: Dan Dixon, Eric Hilton, Georg Steinröhder - Universe Sandbox
2:30 PM would be 14:30 which would be 3 hours and 53 minutes ago. I can't find more information than that on the website but the Ubox developers are probably busy with other things at the event, and I guess they'll post more info/videos/photos/content as soon as they can.
