In case anyone wants to make a modified version, here are some files. (Note that this is really a kludge! I just did it quickly in L^AT_EX and then since I didn't want to spend the time to understand fully the neuralnetwork style, I made the licensing statement in LibreOffice and moved a lot of the bits around with the GIMP. ...Sorry, I guess...?)

Different versions of the final thing:

1. the JPG version
2. a PDF version
3. a PNG version
4. an XCF version

And here are the files I used to make it, which you can tinker with as you want!

1. The actual L^AT_EX source: RWNNA.tex.
2. A LibreOffice file to make the licensing statement: RWNNA_license.odt

Here's what it looks like, by the way:
