Hi,

some people told me that I should send the following to this list ..

I wrote a simple brainf*ck program which reads an ascii art only
consisting of the characters / \ _ | SPACE and NEWLINE from the input and
creates an obfuscated c-program which generates the ascii art as output.
there are some limitations:

	* the byte-lenght of the ascii-art must be a multiple of 2

	* I assume that the cell size of the virtual machine is pretty
	  small (like 8 bit). I'm using the construct [-] to set the
	  current memory cell to zero - and that would take some time on
	  32-bit memory cells when the cell has a value such as -1 (0xff..)

	* I assume that the interpreter has an end-of-file handling which
	  does result in (a) not modifying the current cell, (b) writing 0
	  to the current cell or (c) writing -1 to the current cell.

Here comes the code: <in asciiart.b>

It is primary tested on the Brainf*ck CPU that I will present at this
years Chaos Communication Congress.

2B OR (NOT 2B) That is the question. The answer is FF.
