Russian case, declination and general grammar "wall charts"

[Udut, Kenneth]

Is there such a thing as a wall chart which goes
through the various cases, standard declinations and
just grammar things in general?

I'm thinking of something like a flow chart format.

[if this, then that], perhaps with colors for
the various 'paths' one's logic needs to take
in order to make those split second decisions while
talking with somebody as to the proper ending, etc.

I've heard they exist for Spanish and French as what
is called a "Verb Wall".

If anyone knows of such a thing - perhaps a large
poster, or better still, a bunch of separate
sheets which can be put up all around a room.

Thank you!
