Bars of Black and White is an escape the room game created by Gregory Weir, developer of the popular pixel-horror Flash game (I Fell in Love With) The Majesty of Colors. The adventure involves using a barcode scanner to read clues scattered around the room you're trapped in, with hopes that a key can be found to unlock the door blocking your exit.

Note that a barcode can only be scanned by dragging the red light from left to right. A package containing the scanner will only appear once you've solved the puzzle on your computer screen. (source, video walkthrough)
