A net on the grass and the stones are frisbees, to be thrown from a (little) distance.
At the Tuchola (PL) Go Congress 2004:
Ingo Althöfer from Jena University (Germany) is promoting
Frisbee Robot Go. An artistic picture is
In the 2016 Computer Olympiad (to take place in Leiden (NL) at the end of June 2016), a Frisbee Go simulation will be one of the disciplines: When a player aims for cell (i,j), the stone will go to (i,j) with probability 1 - 4*eps, and to (i-1,j), (i+1,j), (i,j-1), (i,j+1) with probability eps each. A natural choice would be parameter eps = 1/6. This also allows to play the simulation with the help of a 6-sided die.
