Invisible Changes

Thanks to Steven Livingstone for sending me these great visual illusions. They all involve scenes that look static but are actually continuously changing in very hard to detect ways. I thought the Workroom one was excellent, because it seems so obvious -- so there in your face -- once you know what's going on (I had to be told), yet so hard (at least for me) to see. I really like things like that which show up the "seams", so to speak, in our perception, which we are usually oblivious to. Not because there's any fun in belittling our assumed perceptual powers, but because they're illustrative of a truth I think we ought to be aware of.
