Econball
Equation of stock trading simplified to game of moving resizing balls
...Those who change to the majority side lose, and those who change to the minority side win, since it is scaled to the average. Its the same math as Matching Pennies and Odds And Evens game which are Rock Paper Scissors with 2 choices instead of 3 (buy vs sell). You see this in the size of balls changing depending where they move. Think of it as a 2d seesaw surface that never tilts because the masses of balls are adjusted to always balance.
This is the early start of a game based on that econ theory. Econ is boring in number and symbol form, but as a realtime game its more like dancing.
