This is probably the last big idea I had, if I can't dig up others.
It started here: https://www.gamedev.net/topic/676377-local-hash/
Since then, I developed it more:

[edit] The "pencil" source code is now available here (with a working CentOS 7 makefile so far only): https://github.com/dmdware/pencil

And got some results by accident when I was attempting to write a "psychodeloscope" (basically a neural network that would process an image, or a camera capture, as if it's sensing, and the microphone etc, into one array of bits, and through several layers and convolution, and half of the array being hidden, so there is essentially double the amount of bits needed for all input and output, and produce an image on the screen, its "face", and sound, etc). I made a mistake at one point, in how to write expanding circles from the center of the screen, that were necessary, for something I forget, but basically it would actively "dream", by trying to produce an output, that would try to achieve a desired result, with a hidden layer or something with part of the next frame's input containing the prediction of the result of the world, which it would then map to the previous input (hidden and otherwise). The hash or brain would be like a learning algorithm that advances to the next possible combination of bits, skipping all the previous attempted configurations and any in between that don't work for that last mapping and any previous (this can be done iteratively, to make it faster, so that only the last mapping is considered, not all the history of them, so that, say, over 15 years, it might learn slowly like a child). Being functionally complete, and having enough layers (which turned out to be too high, make the idea unusable, except for maybe image manipulation effects as a plug-in in image editting programs perhaps, and may other uses like sound effects), it would be able to turn any output into any output, with consideration of the hidden layer it uses to "talk" to itself. I got an interesting effect. The effects for the bit-twiddling / bit-shifting were so nice, I thought they make a great album cover or are currency-quality like. They were just attempts to apply the mapping to frames from a movie and images. Some of them look like "the fourth plane of hell" or something. I used one of them as the wallpaper and art for my phone. I think there's more images on that page above, not sure, too lazy to check. I also had an idea to make a "dreamhub.com" kind of like a "DreamTube" where people would upload games or videos encoded in the neural format, so others can play it forward, or play around with it. There might be a use for these hashing algorithms as an image storage and compression format, or a video one.
Here are the different hashing algorithms I tried (rather the operations in the hash):
NAND:

NAND version 2, with only 3 operations, not involving a second mask (I don't know what that means, reading from my own notes, but I remember trying to use two masks and two bits of input, instead of just two inputs and one mask, for one output):

NAND-NOR combination, seems broken:

NOR, good:

XNOR (the original one, later found to be functionally incomplete just by itself, although it also had a NAND, but was then superfluous because it had extra levels required for a full amount of mappings, though it did produce the interesting image effect results above):

I also made a "pencil" app on CentOS, that used a NAND hash and you assigned the masks, and the behavior, whether it fed back on itself, whether it was supplied an increasing counter integer, or whether it got a timestamp each time to use as input:

[edit] More:
[Edit] an eg image encoding using the hash could work by mapping the 24-bit pixel index to map to the 24-bit RGB value and the number of bytes would be stored in the file header, or the hash can be mapped to output the color values (maybe in a hidden layer or not) as output to the previous input.
