I like this one from Tricks. Co. – Japan. It is flat and easy to carry but yet allows for several minutes of fun entertainment. Excellent used condition!
A board with a green dot on the left side is show. The board goes behind the magicians back and when brought back the dot is now on the right. Back again, dot jumps back to the left. Audience is not thrilled. The board goes behind the spectators back again and when it is brought back the dot is no red. Again it jumps from side to side, somehow the audience is still not pleased.
Again the board goes behind the magicians back and when it is brought forward it now has a single yellow dot in the center! Now the audience really wants to see the back of the board. The magician complies and now there are a red, green and yellow dot, the colors of a traffic light.
Easy to do with English instructions!
