Thanks.
I don't mean anything special.
Just trying to write very basic 2D interactive game in shell script and have dialog to show options and receive selections and to communicate with a player.
And have another shell script driven graphics application, like ImageMagick to generate mobile image objects.
So the above could work as a fast development platform for developing
some primitive interactive games (brick walls or the like).
And have libraries of objects like in CAD programs and have tools
to manipulate with these objects (written in shell script).

I developed with interactive Google Maps API applications in JavaScript.
Unfortunately JS is to slow and a longer JS script hangs on or slows down MS XP applications run on PC.
So I see no chance to develop any smart interaction in JavaScript.
Mayby shell script runs faster so I need to follow some examples by others to develop a library of shell scripts, library of dialog shell scripts, library of image objects, object manipulation methods, functions ...
And have all that running smoothly one day.

Image processing is great but first I need to learn very basic functions to move image objects on 2D plane/bord.
Chessboard is a good test for me.
Some basic concepts come also from Visual Basic to generate primitive animation with few image objects.
