The world is crying out for a BASH chess engine.
They can enjoy playing chess with this engine on a ship constructed entirely from stones and mortar.
I saw on Mythbusters that a balloon can be constructed from lead foil, along with a concrete glider. So a bash chess program is not alone in its oddness.
Yes, you can produce this engine. The burning question is, "Why?"

Is there actually a way to interact with this green spot on the screen once the program has started?
Haha... you caught me! A chess program in Logo is probably not possible, as I don't recall any way to interact with the turtle (although there might be. I haven't programmed in logo since I was like 10 )
When I wrote that I have just tried a very basic web application, able to let the turtle walk forwards, right, left and so on.
Then I found a more advanced interpreter. FMSLogo has the following features:
FMSLogo includes support for
* "Standard" Logo parsing
* Turtle Graphics
* Exception handling
* TCP/IP networking
* Text in all available system fonts
* 1024 independent turtles
* Bitmapped turtles
* MIDI devices
* Direct I/O for controlling external hardware (must be admin)
* Serial and parallel port communications
* Saving and loading images in BMP format
* Calling into native DLLs
* Creating windows dialog boxes
* Event driven programming (mouse, keyboard, timer)
* Controlling multimedia devices (WAV sound files, CD-ROM control, etc.)
* 3D Perspective drawing (wire-frame and solids)
* Creating animated GIFs
This one could easily be used to program a chess engine. Also the GUI would be pretty fun; with the feature "1024 independent turtles" you could create 32 turtles then in combination with "Bitmapped turtles" put some bmp of chess pieces on them and let them run over a chess board. And finally with "Event driven programming" you could easily interact with the user.

The bigger problem is that Logo was never designed for speed. With its lists, arrays, and tail recursion, it is about as capable as Scheme, but slower due to lots of reparsing and dynamic scoping. And of course garbage collection kills performance. I've only used UCB Logo. Others may be faster.

When my attention drifts from coaxing Brutus to compile natively on Linux, I keep adding code to a project like this. It won't end well.

No, the world will be crying once there is a BASH chess engine.
OK, Ben, feel free to pick it up from here.
Pure bash -- it doesn't even use arrays! http://pastebin.com/f18841718
This UCI engine mostly understands the rules. (See comments to learn its limitations, other than having the ELO of a turnip.)
Check out its fight vs Stockfish (10 min / side)!

I don't want to give the false impression that I'm maintaining this (yuck!) but I noticed that I introduced a bug when I added e.p. captures to the movegen. Since I want to see the engine lose tragically rather than crash, here's a fixed version.
What the f:shock: That's funny! If I register for FICS can I watch this cruelty? (You can PM me; I'd bet I'm the only one here with no internet chess experience.)
