Stereogram Experiment

You have three controls:
  • A red dot at top. Right now, sweep it all the way right and then back to the left.
  • A blue dot at the bottom. Right now, sweep it most of the way right, and then back to the left.
  • A play button in the bottom left corner. Press Play.
While it's playing, the red dot will move by itself. You can use the blue dot. I encourage you to move it into the first green zone. Other places could be interesting, too. If you know how to view stereograms: pause the action, slide both dots all the way left, and use wall-vergence (focus behind the screen).
What's going on here? Eh...I don't have time to explain now, but this is my (so far) best attempt at making stereograms visible to people who may lack depth perception.
