This is a simple animation of global illumination of emissive circles.
Basically, for each pixel, multiple rays are cast which provide light to the pixel if they hit a circle.
Full source code is available on my website.

  • It loots odd to me at first, until I read your description.

    Let me guess though... you stop tracing a ray once it has hit a circle?

    If you followed on to find more intersections, it might look more natural.
