Mike Brister is a theme park designer and I love his 2022 patent directed to a “vanishing illusion system.” U.S. Patent No. 11,235,258 .
The basic idea is that a portion of the glass is reflective while other portions are transparent. But, the room on the other side is a mirror-image room–identical except that for the person trying to see himself in the mirror. A higher tech-version involves moving the mirror/transparent portions for various effects.
Patent examiner issued a first-action allowance on the following claim:
1. A system for generating a vanishing illusion, the system comprising: a first room; a second room, wherein the second room mirrors the first room; a wall separating the first room from the second room, wherein the wall comprises: a transition glass comprising a mirrored portion and a transparent portion; and a frame through which the transition glass is configured to move; and an actuator configured to move the transition glass with respect to the frame such that the mirrored portion is in alignment or out of alignment relative to the frame based on a trigger or a condition being met.

Query: If an illusionist had used something similar to fool audiences in public performances, would it be prior art?
