I made Sift, an experimental image editor that slices an image into layers. You can offset the layers to generate interference patterns and pseudo-3D effects.
sift.constraint.systems

It uses additive blending and a pixel-based light splitting algorithm. It came out of thinking about how to add depth to a grid of pixels. For more info you can read the release notes (writing.grantcuster.com/posts/) or watch a video tour (youtube.com/watch?v=MJQNnAr40V). As always, I'd love to see anything you make with it.
