Maze Code + Polargraph?


My RSS feed for Slashdot brought my attention to an article on Slate.  The Slashdot summary stated:

This Slate article talks about a single line of code — 10 PRINT CHR$ (205.5 + RND (1)); : GOTO 10 — and how it manages to create a complicated maze without the use of a loop, variables and without very complicated syntax.

Even though that “one line” of code really is two lines and it really does use a loop, that short string of code is still very interesting.  While the way the code generates a maze isn’t immediately intuitive, it becomes obvious once you watch a bit of the video above.  All that code does is randomly kick out a forward slash or backward slash.  Once they wrap around to the next line, they start to form what looks like a maze.

As a little exercise I created something similar using PHP.  To make that work I had to use a fair bit of CSS to make it look decent.  In any case, it occurred to me that this would be a wonderful project for a Polargraph! Draw a random forward slash or backslash, get to the end of the line and make a bunch more on the return line.  How awesome would a huge paper roll of nothing but a giant maze look?

I think I may have found a project cool enough to show off at Maker Faire.  :)

    That’s two lines of code, a loop, and not a maze. :head explode: :)
