This demonstrates Edwin Land's (of Polaroid) process by which instead of using three primary colors (Red, Green, Blue) to display a full color image, you instead use just two.
Alternating scanlines are:
  • Just the red component of the original image
  • The green component of the original image, being displayed in the Red, Green, and Blue channels.
    Move the mouse left and right to select the image to process.
    Click to see the original version.
