Different people see different things.
What do you see here?
I was just looking at this glass building, and I thought to myself, it's a huge jigsaw puzzle!
Look at the sizes of the glass panels, it seems almost every piece is of a different shape and size.
Must be a nightmare fixing them up!
Or maybe it's just optical illusion.
Most of it are of the same size and shape but the eye is tricking you into thinking otherwise.
Glass buildings are attractive don't you think?
