playable, brainless, no check for valid moves.
The code is released under BSD type license. Basically, that means
"Do with code whatever you wish, but give a credit if use substantial part of it"
(see enclosed licence.txt)
For version 1.00:
Features that should work:
(+) Figures moved by drag'n'drop
(+) You can do pawn promotion, en passant capture and castling by drag'n'drop, too
(-) It does not chack validity of moves. There are some checks - you cannot
capture your piece for example - but otherwise you can make pretty wild moves.
(Wooden board would not check valid moves either

(+) BUT. Undo function (Action/Take move back) works. So you can always take
back your wild move

(+) Save and load position work. Position saved in standard FEN notation...
(-) ... almost (castling availability always set as "full" (KQkq) and number of
halfmoves since last capture/pawn move always set to 0)
(+) There is "Actions/Flip board" option that works. Even if noone will use it

(actually supposed to be used then playing black against computer)
(+) There is "Move list" window. Wikipedia calls that notation "Reversible Algebraic".
(-) Moves are not saved with position
