The project that he's working on seems a lot like another multimedia DVD that someone put together for the ilovebees.com interactive game they had last year. The game was a tie in to the massively popular Xbox game Halo 2, but it was played across America using pay phones and the internet. I guess if you were able to figure a set of clues it would lead you to a pay phone and to the time it would ring. You would pick it up and it would play a piece of the radio drama they had created. I wasn't involved in the game at all, but someone put together a DVD compiling all of the seperate parts of the Radio Drama, deleted scenes, pictures of some of the players, and original scripts, and I got a copy of it. It was well done. The radio drama itself was several hours long.
It takes a lot of time to build something like that and I understand why you wouldn't necessarily want to give it away after you're done. I guess for me though, if I were to do something as cool as that, I would want to show it off.
Anyway, the ilovebees dvd was a well done project and if baby hum's project is anything like that, then it will be great.
