Excuse my ignorance Almass - but what doesn one do with the parts? Do you have a use for it now? or are they just keep-sakes?
I don't know.
I am thinking of mounting the lens in a frame with an antique coin or stamp to display on a wall somewhere in the house. (Spacing the lens v object)
The Prism. Beside shining a beam of light to see the different light color/wavelength. I dunno what to do with it nor if it has any value. Maybe mount it as a bedside table Lamp. Or probably gift it to some science university Lab.
The Diatronic plate to be mounted on a projection kit to splash on a big wall or a ceiling or a meeting room table or whatever for a company interior design as an Art piece.
I posted a similar picture sometime ago with a model covered by text projected on her. So it is simply using the plate instead but on a fixed space.
