I was thrown down the rabbit hole of possibility when I saw a image on imgur of a wobbly paper rolling shape. I was trying to describe the shape to Leon and couldn't so took a circle bar coaster, ripped it in half, ripped notches and re-assembled and sent it rolling down the bar. That was the best concept demo I have ever given.
The possibilities for this shape are manifold. The first thoughts are of "urban tumbelweeds," free rolling kiosks plastered with show announcements, stickers, lost dog sheets, graffiti. Other thoughts range from unstable sculpture to wobbly city models.
Shape 1: This worked tolerably but was to stable.

I rounded the plywood into a vaguely lunglike shape.
I drew an esoteric gameboard on the concrete of the studio and left it as a game piece for the others to play with.
Later Areli and Leon came back with me to see the shape and determine the rules of the game.
