I like illusions, here is a home made one!
linkMartin Clifford sent in this illusion, and I think it's best to quote him, since he did a great job in explaining it. Here's What Martin wrote: "Hi, I love your illusion site. The other day I was taking a picture and I thought it looked slightly different than it was. I fooled a couple of people with it and also a couple seen it. Any way, some people thought the dog was coming down the stairs and I was taking the picture from the bottom of the stairs. Its not the bet illusion ever but here it is for you anyway." Thanks Martin!
