Well, what can i say, that is all absolutely stunning! I saw the images a short time ago on your DA.com account before reading everything here, and thought it was pretty amazing then, but having looked through the finer details, everything has slotted perfectly into place.
The musical score accompanied by the timing document was attention grabbing, sit up and listen stuff, brought back many fond memories. The hairs on the back of my neck stood up just listening to the soundtrack and thinking about what an experance this would be, so much so, that just the music alone was exciting!
As for the age/intensity issues raised, i think that provided the drop segmant isn't overly forceful, and the emphasis is put on fun, then it could be suitable for a wide range of people. Perhaps a TV advert and other marketing material, featuring a family with kids varying in ages would be useful to promote this?
In regards to patent/copyright issues, i'd definitely reccommend you consider it, now these ideas are out in the open. Could have a peek at the UK Patent Office site - http://www.patent.gov.uk/.
Overall impression - wow, great work!
