An iOS app called The Lost Treasures of Infocom included the "feelies", as 3d models, alongside implementations of the games. Sadly, it is no longer available due to lack of backward compatibility (they never bothered to update the app for newer OS versions).
I have that for windows. I believe it came with a bunch of floppies and a book with images of the hints for all the games.
I also have hitchhiker's guide, with the panic sensitive sunglasses (black cardboard glasses with no eyeholes), pocket fluff (a cotton ball) and a microscopic space fleet (an empty clear plastic bag - afaik)
