So, what if we invent a prank that’s also a creative masterpiece—like a pop‑up mural that only shows its true image when you tilt the room or press a hidden button?

That’s the vibe—maybe a button disguised as a coffee mug on the shelf, and when you tilt the room, the easel pops up like a magician’s hat. Just don’t forget to hide the cue so the audience thinks they’re watching a normal art show before the grand reveal.
