After seeing the video, I obviously had to make it work. Occom's razor and I have produced a "this would work" version. (For intellectual reasons, this will not be performed prior to a working model captured on video which has been stamped 'okay to use' by Sean- 'cause stealing -even ideas- is grimy)
In leu of divulging anything but for want to answer a question:
You could definitely preform this at college w/ a text book, a library with a book from a shelf or, depending on situation, anywhere you are so long as you have your back pack and a book or two- and chances are if you have a backpack, you're a student and if you're a student, you should have at least one book- academic or not. (If you're in search of a book that is not academically related, may I suggest The Paper Engine by Aaron Fisher- just finished it for the first time, looking forward to reading it again)
Hope that helps and i also hope i didn't step on any toes- I've only recently tuned into your magic Sean but I am more than intrigued...
Always,
David
