Project Idea vol.1

Project Idea

-Air Screen-

There are 4 painted pedals on the Servo Motor which linked to the switch nearby.
With switch on, 4 padals will rotate horizontally and show some picture.
Hopefully it has a sound interaction also.
This is going to be a wall decoration, especially set up indoor, i.e. museum or exhibition hall.
4 pedal should be counted as 1 unit.
If million units can be shown as a huge decoration, very eye catching.
Each unit should be painted different colors.
