What would you use it for? I'm pretty sure this is possible, anyways.
I know it's possible, hence my asking.
The original idea I had was for Mini Empires, it seems like it would be a nice thing to have to save people the small trouble of eventing shinking and growing. Aside from that, it'd be a fun element to throw into DM's. For example, a house would make a decent arena for a DM, though it's pretty plain at just that. However, if you made little mouse tunnels everywhere, you could create some interesting ambushes and the like, as well as interesting face offs with the players constantly changing sizes. I'm sure there are plenty of other uses, especially if the host can change what size the players resize to, possibly creating some kind of "Mario" element as well.
