It would be nice to develop some generic game mechanics around systems where combinations of parameters produce a "zoo" of entities. In particular, when parameters are "freedoms" for entities. It will make sense in a minute, hopefully.
For example, consider quadrilaterals. If you make all sides and all angles equal, you get squares. Relax angle requirement, get rhombuses. Relax side requirement, get rectangles, etc.
Or consider Colleen's Thinking Blocks

You can view number types (natural, whole, fractions) as having more and more freedom.
At Richard's presentation, he talked about a zoo of polyhedra, with a very nice way of turning five types of freedoms (e.g. convex polygons, interchangeable faces) on and off. You can see the slides here:

Sooo, maybe we can have a talk about this type of systems and their game mechanics some time in June or July, too? There got to be similarities there. And "freedom" (or gaining more or less of it) is a nice setup for roleplay. I started to sketch a game called "Squares go everywhere" about creatures that can morph their bodies and are allowed into different territories based on that (.swf attached).
