If you're curious what an implementation looks like: Charlie Gerard's article[1] shows how to accomplish a similar effect in-browser. It's pretty straight forward although not sure what performance looks like in large scenes.

I like the idea, but don't know if people are ready to grant webcam permissions to untrusted any websites.
