Experimental garbage

I have a craving and desire for a game, but it doesn't seem to exist, nor do I even have any idea what it is anyway, so here's an idea....

I'm proposing a highly experimental game. I doubt it'll last long, but I want to see what we can do with it. I'll just need people to actually try it with me....

The idea is- you can play just about anything. When you drop into the game (at least at first), it's an endless white void. The characters can create just about anything they have the creative and detailed capacity to, as long as that thing isn't alive (excluding plants).

Yes, it's vague, and yes, vague things fall apart, but I just want to see if we can get any kind of structure or story out of this whatsoever. The setting is both everything and nothing. It's all about character interaction.

..... Thoughts? Any interest?
