Stills from Lightstream, help please on info and Creative Commons guidance

I have some photos and video from Lightstream in Fore Street on Saturday but not enough information.  Is Lightstream the general title for all three works or just for the one by Tal Rosner? What are the other titles and where did they come from?

Also is there explicit guidance on Creative Commons? I guess it is ok to photo / video / record sound and then edit / remix but am not sure. If there was an explicit statement it could help to generate more interest as well as new content. See the video interview from Isca Obscura aboutv three minutes in.

Also, what will happen with the talk originally intended for Spacex? Will there be an online archive at Soundcloud or somewhere? If Creative Commons it could be downloaded and used as part of something else.
