Can you point me at some videos of the OpenVCE.net 3D Space facilities and I-Rooms in Use?

Short version of the VCE Tour:

  • http://openvce.net/vce-tour
  • 4 video formats there.
  • Shockwave one is laid our nice... I had to refresh the web page to make the Shockwave widgets load.

Meeting we held between Edinburgh when you were here and Norfolk is at:
     http://openvce.net/event-openvce-meet1
     After event recording is in password protected area (user name and password available via a.tate@ed.ac.uk).
     It will be best to download the 500MB (!) .wmv movie in advance and not try to play it over the internet.

But a short meeting in an I-Room might give a better idea of what we normally do for active meeting support.  Try this YouTube video of a meeting related to supporting a team producing a multimedia product like a game.. the team meeting here are in Edinburgh, Glasgow and Malaysia.
