Was testing some Dirac/VC2 stuff, ended up with this
5_3 wavelet (LeGall), 2 transform levels, qindex is 38 (average across all slices), 32x16 slices.

Dug up some more unintentional
This was generated by libaom d5565bba29 with the Daala distortion experiment, the tx64x64 experiment and the qm experiment turned on.

Unintentional
Monochrome AV1 with a desync.
I should make a bigger version and use it as a wallpaper.

Found some more unintentional .
I think this one had to do with a botched shift from 8bit to signed 16bit. And some sort of chroma desync too.

Some more unintentional(?) happening because of that.
Oh and Twitch have been saying how they'll introduce VP9 for lower-quality transcodes of streams for 1.5 years now. Still not happening, despite them saying at demuxed this year it was almost done. Some people even believed its already used.
It would be bad quality anyway because it'll be FPGA-encoded, so probably worse than any hardware decoder.
