i am trying to build a "demonstrator kit" to aid in selling lens options. does anyone know of anything that already exists/ or is marketed?

my ideas so far:
-6.00 in CR-39
-6.00 in 1.67
-6.00 in A/R 1.67
various tints.
scratch coating demo
a Transitions demonstrator.
polarized demonstrator
a sample FT28, next to a PAL.

does anyone else have any ideas? I'd like to get this in 1 handy display that would fit on a small shelf, and my optician can go through options systematically. thanks in advance!
