[Etoys] Matrix morph idea

[karl]

Holders are a great tool and is kind of a all round collection, it grows 
and shrinks when elements are added,and elements are pushed up and left. 
This works great but I was wondering if an matrix kind of Holder would 
be interesting, where each cell is numbered and it would be possible to 
reference positions etc. Kind of a Kedama but with possibility to drag 
and drop object onto the grid, to make tile games like checkers. One 
benefit of a matrix would be that it would be easier to check for 
patterns in the grid and thereby make simple computer players. What do 
you think ?
