Amazing T-Rex Illusion!
This is based on the famous dragon illusion which was inspired by Jerry Andrus.
This is a wonderful optical illusion. This little dragon is made out of paper – you simply cut it out and stick it together, and stand it on a table or window ledge. But when you move around, the dragon’s head seems to follow you around the room. Have a look at the video, to see what we mean. The effect is really uncanny.
