+Choose people or things at random using Bangle.js.

+
+## Usage
+
+You can use Choozi to pick a person to play first in a board game. With all
+the players seated in a circle, set the number of segments equal to the number
+of players, ensure that each person knows which colour represents them, and then
+choose a segment. After a short animation, the chosen segment will fill the screen.
+
+You can use Choozi to randomly select an element from any set with 2 to 13 members,
+as long as you can define a bijection between members of the set and coloured
+segments on the Bangle.js display.
+
+## Controls
+
+BTN1: increase the number of segments
+BTN2: choose a segment at random
+BTN3: decrease the number of segments
