If you are the kind of magician that likes pack flat props that occupy negligible space in your magic bag, and play for a large audience to provide several minutes of solid entertainment, you will find this an excellent item, and outstanding value for the money. A Daffy Dots clone, with six changes, that uses no flaps, switches, or duplicate boards.
The bare bones of the effect are as follows.
The performer displays a picture of a "traffic light" with four spots on it. The top "light" is green in color, and the other three red.
The picture is passed behind the performer's back, and the green light is now second from top. Passed behind the back once again, it is third from top, and finally at the bottom.
The audience is not impressed, as most of them have figured out "how its done". They ask you to show the other side.
You do this, and there are now four different colored spots on the opposite side. Then you turn it around once again, and there are a whole variety of multi-color "spots" on the opposite side.
The entertainment lies in the amusing patter theme as you make the changes, which we have outlined for the city of Calcutta, but which you could easily adapt to any city with chaotic traffic conditions.
Easy to do, with a clever secret, and great entertainment value.
