In one of L.M.Montgomery's stories, Emily ( of New Moon) could do optical tricks with wallpaper.
As a child, in bed because of mumps, measles or whatever other current virus I had enthusiastically embraced, I played eye-games with the floral patterns of the wallpaper in my bedroom. Hiding among the petals, running along the maze of patterns and spirals and vines, leaping from bouquet to bouquet.
Another amusement was imagining my bedroom - or any room - upside down. I found the spacial alteration of door and window casings particularly fascinating.
