And now for something completely different ...
While browsing about this morning I came across this interesting announcement - a MIPS optimized build of a very bizarre, Turing complete language/compiler with an amusing name:
"For all the SGI brainf* developers out there, I'd like to introduce Thalion Graphic Solutions eK. bf-sgi-1.0, the brand-new, MIPS-optimized implementation of Urban Mueller's infamous creation, the programming language brainf*.
It translates brainf*-source to Mips n32 code on the fly, and is thus able to run your brainf*-programs at native system speed.
Supported platform(s):
SGI Irix systems able to run mips3/mips4-n32 code.
Get the (gpl'ed) source distribution at
http://www.thalion-graphics.de/download/bf-sgi-1.0.zip
and the binary-only package at http://www.thalion-graphics.de/download/bf-sgi-1.0-bin.zip
If you don't know, what it is good for, read more about brainf*, for example, at
http://www.muppetlabs.com/~breadbox/bf/ or search metacrawler ...
Have fun with it :)
Regards
Helmut Schulz
Thalion Graphic Solutions eK"
If nothing else, check out some of the source code available for this thing -- it's quite interesting to say the least.
