The demo for the Virtual Reality Notre Dame Cathedral Project, has been released. This odd, but very cool project, is an accurate representation of the Notre Dame Cathedral rendered entirely using the Unreal engine - and yes, it's multiplayer. Here's a features list for those of you not familiar with the project, which does not require Unreal:

• Explore the cathedral in full detail, for as long as you like.
• Take photo-snapshots of anything inside the cathedral and save them.
• Take a guided tour by a genuine virtual friar tour guide.
• Learn about the history and heritage of Notre-Dame de Paris.
• Engage in interesting conversations with real historians and architects.
• Chat with other visitors, make new friends.

I can't seem to get the download link to work on my end, but it might be my problem or a temporary glitch.
