Cool that you can make a NAND gate like this, but I was more hoping for something that showed how to practically (ab)use a video encoder for "great computational power" to do something real. Not just how to make a NAND gate with one.

I was hoping for some variant of the FORCEDENTRY iPhone Messages exploit, which built an entire CPU with the PDF fax blitting operations.
Fair enough. Maybe not that far, but perhaps do a little one thing with these NAND gates they theorized? My issue may even be more with the HN title than the blog post, because the post never suggests anything like using a video codec for "great computational power".
I tried looking it up but failed to find any technical write ups of how this was done, do you have any links maybe? Super interesting to read.

I wonder how much overhead that incurs (i.e. how much slower the exploit code is in the JBIG "VM" versus native).
