Poo Go
Poo Go is an untraditional way of playing Go. In my family we use the german term "Klo-Go", which could be translated go "Toilet Go". Basically, you play Go while sitting on the toilet.
I am playing this with my father very often. We have a piece of squared paper fixed on the wall in front of the toilet bowl and a pencil lying on the windowsill. It's kind of pen & paper Go, with a square and filled/empty circles, usually 13x13, it would last too long otherwise: Whenever one of us is on the toilet - and it's his turn - he is making a move.
Such games get very interesting, as you can think about your move for half of the day.
Additional tip:
- After the fuseki, we use arrows made out of post-its to mark the last move, so we don't have to search for the new stone.
