I've talked about this with a few people and they seem to think it would be pretty fun to do.
Using the projection screens and a little bit of video editing, you could do a pretty cool "scripted' presentation with a pseudo-interactive character (possibly the presenter him/herself). Given the correct scaling and timing, one could walk over to the screen and then contine "in the screen" or carry on a conversation with themself.
I have some background in some small film projects and this is one idea I've had brewing for a while now. I just think it would a neat endeavor to pursue. I mentioned it to Klein and he raised an eyebrow at it, although he's pretty busy all around.
Thoughts?
