Carmen's Kaleidescopes

Carmen had a collection of over 90 kaleidoscopes.   She had all types but there was one that I really liked. In fact, it is the only one that I am planning on keeping in her collection. (I've been passing some on to family, and her sister will get the bulk of the collection.)

It is made of glass and metal and when you look through it you see... a ever changing rose window.  It looks like the window in the back of my parish church.

Coincidence?
