You might try contacting the Science On Wheels program at Pacific Science
Center. When I was there we made our own using plastic sheet magnifiers and
safety goggles.  They only shifted vision about 5 degrees  but it was plenty
to notice the effect.  I am thinking that 30 degrees would take quite awhile
to adapt to.  The brain can shift 5 degrees in about 10 - 15 minutes.
