Description of Game - Architecture Layers

There are 4 layers to the set of educational games I've been trying to create, called FunFunctions:

1. 2d-3d visual/spatial math games

2. authoring interface that connects games to 3d landscapes.  The solutions only have to have (x, y, z) points or lines.  Then they can be shown in any landscape. Teachers can control it more.

3. the landscapes are shapes, "billboards" and buildings placed on a terrain. Architectual students could build them, such as by using Auto CAD.

4. cognitive tutor: All the games would be displayed on a pallette that only shows games that are

a.  appropriate to the player's math level, 

b. favorites: the player's choice of conquered modules , or 

c. teachers' guidance could add more.

To begin with,  I want to get a full game running. I've had little ones running about 1993 and 2002, but I need to do this again and am thinking of using the a mobile handheld, combined with Google Earth and GigaPan. (The handdrawn sketch from the last blog applies to this).
