LED 'screen' that will toggle between two images for cheap? Answered
I'm looking to make a prop soon that is basically a backpack with a small screen on it. Said screen alters between two states: green with a smiley face, or red with a rather angry looking face.
I am looking to make it so I can alter said screen between the two states, for as cheap as possible.
My first thought was to have three pieces of plexi: one with the smile, one with the angry face, and one blank, putting the blank one in the middle. Then, light the edges of the other two with the corresponding colors. However, I don't know how well that would work, or if there is a better option.
Thanks in advance!
