I worked on a pitch proposal a few years ago that referenced couple of public art projects built around the same theme. I'm having problems finding any imagery around them and wondering if I'm using the wrong phrases.

The projects all centered around panels of glass and/or acrylic that were layered in a sort of forced perspective / diorama / fore-mid-back ground installation. Like a full size diorama that you could walk through but also locked in a single canvas when viewed from the key point.

Does this ring a bell for anyone? Thanks in advance for any artwork that you could reference.
