extremely cool
I’ve seen this embedded within geographic paths that form polygons. There are many points along each side of a polygon, arranged so that each segment length is longer (1) or shorter (0) than the one before. Decrypts to two floats, offsets from the first point.
I have always been a "hacker" at heart. Although I couldn't express my thoughts on the guy publicly, I DID add a new linetype to the file which sets them in Autocad which had a rude message about him. The scale was so small It looked like a solid line, but if you were in the file and zoomed in you could see it repeated over and over.
Thinking back, I don't know if any files with that linetype went out to consultants, but if they did the consultants either didn't catch it or kept my secret.
I used to do this when I designed rave flyers in the 1990s.
tell us more?

Oh, interesting. What was the meaning of the offsets?
We could store an arbitrary path in a database in the clear, and only with a decryption key find a dropped point.

I encoded secret messages in rave flyers I designed in the mid-late 1990's, in Los Angeles. I couldn't tell you what the messages said now, I just remember that I did it. The messages were encoded in a border design, much like the subject of this article. I may still have an example somewhere, but finding it in my digital hoard is going to be a problem.
some cutting edge stuff for the time, as well as some awful design!
