Another short story where there is a special room with full-screen walls, and whatever these kids think about is displayed on the walls and then comes to life. They end up spending a lot of time in the room. The parents threaten to lock the room off. The story ends with the kids resolving the conflict by tricking the parents and locking the parents in the room. Then the kids think about tigers, and the parents are eaten.
Ray Bradbury, The Veldt.
This is the Ray Bradbury short story “The Veldt.” From Wikipedia: “The Hadley family lives in an automated house called ‘The Happylife Home’ …. The two children become fascinated with the ‘nursery,’ a virtual reality room that is able to connect with the children telepathically to reproduce any place they imagine.”
I think this is “The Veldt”, by Ray Bradbury.
