If you've seen any of the Maurits Escher's works, you'll know what we're talking about. When trying to run the program with command line arguments, be generous. Selected Author's Comments: BEMAZING ======== "You're in a twisty little maze of beams, all different." Bemazing is "amazing" taken one step (letter) further. Bemazing creates a 3D maze of beams. Try to go from the entrance (the unfinished beam in one corner) to the exit (the unfinished beam in the opposite corner) or vice versa. For maximum portability, Bemazing is not tied to any window system, but creates postscript. The picture it makes will fit on either A4 or letter size paper. In addition, because postscript is rather verbose, Bemazing creates the postscript in gzip format, in order to save precious bits on your hard disk for the latest version of GNU Emacs (after all, you wouldn't want to use an editor without a psychoanalyze-pinhead function, now would you). Again for maximum portability, Bemazing will take special care that the binary output will not contain any newline or return characters that may get weird treatment on systems that do not use the One True Line Separator. NOTES ===== Be sure to view the source with something that can display characters \240-\377. Use LESSCHARSET=latin1, M-x standard-display-european in GNU Emacs etc. The source does not use characters in the range \200-\237 (we are not an unnamed word processor that tends to create HTML containing these control characters). Because this is not the obfuscated postscript contest, the postscript does not contain any "for", "if" or other control structures. All the logic is in the C code. There are only a few straightforward "def"s, because otherwise the output would become much larger. Try running Bemazing with command line arguments and see what happens. (But note that the program only guarantees that there actually is a route from entrance to exit if you run it without command line arguments.)
