The result was a huge loss of detail, and very exaggerated edges. Obviously I could tweak the energy function and maybe get something better, but it's probably not worth it.

Another weird dithering experiment, I consider this one a failure.
This one was simulated annealing, trying to match a Gaussian blurred candidate image to the Gaussian blurred target image, with a tiny penalty for differing from the unblurred target pixels to keep it somewhat grounded in reality.

Here it is with the CGA colour palette for something slightly more practical. I also tried with the WebSafe color palette, but the difference between the two ceases to be visually apparent at that point.

I wanted to try an experiment with dithering:
- Find the pixel in the image that hasn't been quantized yet that would result in the lowest quantization error, and quantize it.
- Distribute the residual error to all remaining pixels that haven't been quantized using inverse square distance.
- Find the pixel in the image that hasn't been quantized yet that would result in the lowest quantization error, and quantize it.
- Distribute the residual error to all remaining pixels that haven't been quantized using inverse square distance.

Of course it's only going to display the first frame of an animated WebP image. How silly of me to think otherwise. Let me try that again.

I wanted to create a reusable Golang package for creating video files, and of course I needed a demo to test it. A lot of yak shaving later and I somehow have this completely over engineered Munching Square animation.
