Illusion
by Amil
A mirage is something that you see which is not there. For example when you're in a desert you see illusions if you see water but it's really not there.
A spiral is like the round staircase in Sir John Soane's Museum. There's a round staircase and it's made step by step.
A perspective is a picture that looks like it's far away but it isn't, it's flat.
A mirror is something you look in to see your reflection. You could make lots
of different illusions with them. In Sir John Soane's Museum there's a room
where they put a little mirror in the corner at the top of the room. It looks
like there's another room but there is not.
