- I was in Portland OR. last oct. and went to the OMSI (Oregon museum of
- science and industry) and they had a similar device on display, it was
- set up as a kind of ride but unfortunately it needed a part fixed to
- be operational and i live in alaska.
-
- it was desinged as a system of rings that when you where straped in
- you could swivel in 360 degress of movement, it had no power to it, so
- you were on you own to get it moving...
-
- i was thinking you could hook it up to a computer system, run moters
- and gears to the rings, hook it up with a headset and data gloves and
- be in buisiness...
-
- the ring set up was bought from a local athletic store (i have the
- phone number at home somethere) and the price was around 4000$ not bad
- if you ask me..i'll get all the info i can on this thing and post a
- more proffesional article when i get my stuff together and get some
- time to put it together...give me a week or so..
-
- if anybody knows of a system that is already put together..i'd like to
- know about it..but as far as i know no one has and is trying to sell
- them... hmm...

- [MODERATOR'S NOTE: At the recent IAAPA (amusement part association)
- conference in Dallas, I saw at least three firms advertising and in
- two cases demonstrating these ring devices. They are not motor driven
- or computer-controlled. The "rider" provides the energy and the rings
- respond like a gyroscope to rider movements. Not very profound but
- apparently relatively cheap and very profitable. -- Bob Jacobson]
