Hi Loons, you're so hi-tech. How did you make that toy ?

With the ugliest Matlab code ever written ;p. Actually, MATLAB's animated GIF functionality is the ugly aspect. |

Here's a Go Seigen game, using just normal sgftopng. If I was to create it now I'd use the hacks I added to it so the board and stones look nicer (at the expense of a heavier GIF)

Well, yes, but no... The animated gif result is 136 mb  Gif is very, very inefficient for compressing. I'm now running gifscile with O3 to see if it gets smaller. Will report back after groceries

Will report back after groceries You can download the optimised 98MB file (yikes) from here. (it is from my Public Dropbox folder, so it may go eventually, as of now it is still uploading so wait 30 minutes or so, I have shitty upload speed.) I just downloaded and APNG encoder, maybe animated pngs are better optimised (or Webp, I'll try that instead later, maybe.) A good delta-frame-compressor should get the file pretty small, since stones and non-stoned areas are always the same, so the deltas are pretty straightforward |

Holy sh*t. Converted to apng (well, recreated as apng.) Apng is a well, not-very-implemented standard, with animated pngs with alpha channels. You can have it in Chrome with a plugin/development version, in Safari v>8 and any Firefox. The file is a whooping 2.3 MB. For comparison, the image with an empty board or a few stones is ~1MB. Behind hide tags, as I said it will only animate on Firefox straight out of the box. |

Awesome! Here’s the Chrome plugin: APNG for Chrome, “Animated PNG support for WebKit/Blink browsers” |

Chrome on iOS 8.2 works, too. |

I guess then Safari on iOS 8.2 also works (unless Apple has changed how it makes 2-nd party browsers work, Chrome uses the same renderer and JS engine as Safari) |
