This was my other "too long for OPC5" obfuscation (the other was The Best Ever). It is a boustrophedon.

The README file said:
0) I shouldn't tell anything: once you've run it, what it does is obvious.
1) One hint: it has two modes, depending on its command-line parameters...
3) Try these: x .404 y -.35703 w 5 h 5 i 108 z .9 A -.3 a .3 n 100 and save the result in a file
4) Then play it with PgUp/PgDn in an advanced enough text editor.
5) It doesn't fit in any of this year's categories. :-(
